Cyclohexane Chairs

Рет қаралды 279,409

Cyclohexane makes weird shapes! The most important is the chair conformation. Here we will learn how to draw cyclohexane chairs, how to flip them, the difference in energy between the two chair conformations, and between axial and equatorial substituents. Chairs are easy place to lose points on exams if you don't draw them just right!

Here we are again, night before the exam. Will I pass… or will I watch a whole series of Professor Dave explaining chapters of material intended for moderate consumption in a matter of hours. Godspeed gentleman.

A tip for knowing which direction to draw equatorial positions: Make sure the line is parallel to the bond 2 bonds over (either direction works)

@NewWesternFront Жыл бұрын

but then how do you know which direction to draw the first equatorial position??? ahhhhhh Dave didnt check comprehension we're all gonna DIE!!!!!!!!!!!!

Hi Dave! Loved the way you explained them! Can I classify the conformations with their responding strains as followings? Staggered = no torsional strains Anti = No Strains Gauche = Steric Strains Eclipsed = Torsional Strains

@ProfessorDaveExplains 8 жыл бұрын

+Milton Chow hmm, I've never really thought of it that way, but i suppose it makes sense. however, let's just say that anti involves the least possible amount of steric hindrance, though not necessarily zero.
