7 жыл бұрын

This organic chemistry video tutorial provides the mechanism of the fischer esterification reaction which converts a carboxylic acid into an ester using an alcohol and an acid catalyst. This reaction is found in the carboxylic acid derivatives reaction section in your orgo text book. This video contains plenty of examples and practice problems. Molecules used in this video are acetic acid, ethanol, methanol and benzoic acid just to name a few.

Thank you so much for all of the work you've put into making your channel. The quality of your tutorials is unprecedented. I'm procrastinating the hell out of an organic chemistry lab report on Fischer esterification that's due tonight, as any good student would, and this video is a huge help.

i love how you draw the lone pairs out and everything so clearly! It's so easy to follow, thank you a millionnn !!

I love that you teach us these simple tricks about what product will be formed. I've been drawing out the full mechanism for each reaction, and while my professor requires that for a lot of the problems, this helps me know I've arrived at the correct answer.

finally makes so much sense for the intermediate proton transferring part, i cldnt figure out how it jump that far till now i learned its from sovolysis deprotonate n protonate ! thanks a millions for the life saving vdo!!

Thank you. So the lesson here: if u don't want to fuck up your reaction, u better have quite an amount of excess alcohol. Increase H+ would be helpful to increase reaction rate to some extent.

Could you have used the Cl ion from the acid catalyst to deprotonate the methanol attached to the tetrahedral intermediate? Or does it have to be the solvent that does this?

You can use the Cl-ion also

I'm pretty sure HCl would ruin it. You need H2SO4, it's not a good NU like HCl.

Is it becuz HCl vaporizes or something? I remember that whenever I handle HCl, it smells very bad, so I have to do it in a fume hood.

HCl will ruin it so you add pyridine to serve as a base and neutralize all HCl.

The maximum percentage of HCl is 37% in water, therefore 63% of the HCl solution is water and would shift the equilibrium to the left and form reactants over products.
