Don't know if he is gonna teach me chemistry or beat me up ?

thanks! lets go on a date

It was Chem 122. Your videos were just what I needed. I was able to keep going back to them to review as well. It helped my comprehension tremendously. You are great at giving simple, easy to understand explanations. Thanks again. Tedie

This is an extremely helpful video that quickly summarizes an hour long lecture. Thank you!

Can I just say that you literally just saved my life in less that 10 minutes ! Thank you so much for this video, short sweet and to the point !

Nice video, but I believe there are several places in the lecture where he says "hydride ion" but he should have said "hydrogen ion". Hydride is the ion with a negative charge, while hydrogen ion is the proton

You're welcome! Happy to hear it helped you with your project! :)

m indian and watched ur video it has solved all my doubts this was really helpful thank u

You are absolutely right :) Pretty big difference between the two. I'll correct that mistake when I reshoot the videos this summer.

Great Video. This has really helped me out and now I understand what is on my chemistry quiz. Thanks!

Hey man, I don't think I remembered to thank you for helping me pass my chem class last semester. Not only did I pass, but I got a B in a class that I had been sure I was going to fail!! Thank you so much for all your help. T

Andrey...Your lecture is nice, clear and precise talking about all types of acids and bases under one umbrella.

Basically, yes. As long as a cation contains an empty orbital that can interact with a pair of electrons, it can act as a lewis acid.

Thank you for your teaching skills! Much Appreciated

This really helped, got a test tomorrow! Your devilish good looks were distracting tho

Hey Ted, Great to hear that! I really appreciate you coming back and writing this comment. Its a really rewarding feeling to know that my videos actually helped you score well in the class! Was this a general chemistry course? - Andrey

Thanks for this video, My teacher tried to explain this an di had no idea what he was going on. This really helped, THANKS!

Glad it helped!

lol you're welcome ! Happy that it cleared up any confusion!

Wow, you sound super different now compared to 5 years ago. But as your voice changed, your teaching has gotten better as well.

In the first reaction HCL dissociates completely in water because it is a strong acid ,so the reaction should be in one direction HCL ---> H+ + CL- (no reversibility here)as well as NAOH--->Na+ +OH- (in water).

Great video. My students will have a lot of things to learn by tomorrow's meeting in class.

Can't focus. Too attractive.

Thanks for this. Really helped me a lot.

Thanks sir... Great explanation

Good Video! Thanks

Thank you for the video. I have a question though- when the NH3 is dissolved in water(as shown in the bronsted lory concept), it DOES end up releasing OH ions, so how come it was said that the Arrhenius definition doesn't fit for NH3?

This is badassed!

In Bronsted-Lowry, water serves as a buffer, I never really considered that before.

i like the way you present information! :)

This is really helpful thank you.

You rock it Sir

Correct me if I'm wrong, but when you metion a Bronsted-Lowry base, wouldn't it be accepting a hydrogen ion (H+) using the lone pair of electrons from the base? I guess if you say that it's accepting a hydride( which means H(-) having two electrons already), then it wouldn't make sense that the base would be donating electrons to it.

Bronstead proposed that H+ is as proton not an hydride ion....

Why can't the world teach like this.

I'm distracted by your handsomeness. I've learned nothing

Thanx sir very useful for us good job

Thank you

Im finding it hard to make out what you called the bond type when a covalent bond is formed with both electrons coming from one molecule.

youuare theeeeee best teacher ever!!! infinite like for what you're doing!

thank you for your help you are great.

hey i have a question. so any cation is a lewis acid? thank you for the post!

wait so basically, reactants in every chemical reaction have one that acts as lewis/bronsted-lowry acid and other that acts as lewis/bronsted-lowry base?

Damn, you explained it even better than my chem teacher

I think you meant at 6:24 that Boron has 3 F's (and not 3 H's as you said).

it is to good but I want to ask how does water act in lewis arhenious and lowry bronsted theories

Thaaaaaanks maan thats really helped !!

great for ap chem

Nice video sir

Like the guy below, I TOO don't want to be THAT GUY.. but molecular bonding for H2O has the two lone pairs of electrons on ONE side.. to allow the 105 degrees of separation between the two hydrogen atoms. 2.5 degrees per pair of electrons and 107 degrees is normal without pairs for bent bonds. Not that big of a deal.. but that's how the charges are created to allow the bonding with the third hydrogen atom in hydronium. Otherwise.. fantastic videos. I've learned a lot from your videos. Thank you.

last video i saw him is that his hair style changed.

Thanks a lot

😂😂😂i cant stop ma laugh after rd the comments . btw thnx for this lecture "sir"

Sorry to nit pick, Andrey, but you really shouldn't call H+ a "hydride ion." It could get confusing. H- is the hydride ion. H+ is often just called a "proton." Hydride ion chemistry is a lot less common than H+ chemistry, and high-school level students usually do not learn about it, but it's out there.

At minute 6:40,in the example of Lewis Acid. How could BF3 accept a pair of electrons from the hydrogen if H has only one electron and it is not related to any other atome.This reaction make more sens with NH3 molecule. BF3+ :NH3 --->F3B:NH3

But, It was a good video. Thanks!

Andrey is the🐐

Thanks for the good video

It took me a long time until I found this video

Love from India ..! Aligarh Muslim University!

Hydride is H- not H+ (A hydrogen ion, aka a proton)

The Rambo of the white board has spoken.

first rule of fight club: NEVER ABOUT FIGHT CLUB

Great!!

nice

Thank you so much but i have a question why in the reaction you draw two arrows instead of one arrow ??

You the goat 😎

Good

Actually this topic was in our syllabus in grade 11 (in India) but I was still confused between the three. So now one year later I'm watching this and it really helped. Thanks 👍🏻✨

Are you saying quarter covalent? or coordinate covalent...

smart and handsome a rarity!

I cant concentrate.. too focused on his bod.

how can water be acid or base or what makes it act as an acid sometimes or base sometimes ?

Hydride is H- and not H+.

thank you so much. i was on the verge of giving up until i saw your video. university notes are so fucking shit

how does hydrogen have 2 electrons?

hii sir

I am slightly confused by you saying, "donate a Hydride ion." I understand Bronsted-Lowrey acid as donation of a proton, and subsequent association of the Proton to a H2O. Maybe I am just playing a game of semantics here, but you may confuse someone.

sideview this guy looks like Jim.....great lecture anyway

You should try in acting...handsome

hydrogen has single electron... hw is it possible to have lone pair?

help me

bro you are getting them mixed up im like 90% sure you goofed

a luis miguel le falla el coco(8)! F T W

GUY" HAHAHA CUTE.

Not trying to be "that guy" -- but wanted to share just in case someone was confused about anything here: In dealing with the Brønsted-Lowry definitions, at the bottom where there is the molecule of HNO3, the N should have a +1 charge (overall charge on the molecule is 0); on the right side of the equilibrium, the O at the bottom of the NO3 molecule should have a -1 charge (just as the right O does -- exact same thing) and the central atom N should have (like before) a +1 charge (overall charge is -1). Again -- realllllly not trying to be "that guy." Where is your accent from?

WTH! Western peeps study too🤯

you could be lucifer and i wouldn’t be mad
