Draw all three staggered conformations for the following compound, viewed along the C₂-C3 bond. Determine which conformation is the most stable, taking into account gauche interactions and hydrogen-bonding interactions. (J. Phys. Chem. A 2001, 105, 6991-6997) Provide a reason for your choice by identifying all of the interactions that led to your decision. H H&COH C₂ C3 HỌ CH CH3 Which of the following is the most stable staggered conformer? Me H OH Me OH Me- Me Me H Conformer A OH OH OH HO H H H Conformer B Conformer C Me Conformer B because the anti OH groups avoid hydrogen bonding, which is a destabilizing effect. Conformer A because there are only two gauche interactions, and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer C because there is no steric strain for Me-OH gauche interactions and hydrogen bonding between the two OH groups is a stabilizing effect. Conformer B because the large OH groups are anti to each other.
