Cyclohexane Chairs

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.

@inversedq2190 Год назад

Did you pass?

@ProfessorDaveExplains 8 лет назад

+soap2soap very common misconception! happy to clarify.

@yongchinchong3787 5 лет назад

I still don't understand it. Can you explain it to me again? Thanks!!

@luftatmer 4 года назад

@@ProfessorDaveExplains 12:33 ins't the cis-/trans-concept only applicable on structures with double bonds?

@ProfessorDaveExplains 4 года назад

Nope, it applies to rings as well.

@kiandebeste5455 3 года назад

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 Год назад

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

@miltonincsw 8 лет назад

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 лет назад

+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.
