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)

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.
