- 8. Which of the following is the most stable staggered conformer? Me H OH Me Me OH Me OH Me H Conformer A OH HO H Conformer B OH H H Me Conformer C a. Conformer B because the anti OH groups avoid hydrogen bonding, which is a destabilizing effect. b. Conformer A because there are only two gauche interactions, and hydrogen bonding between the two OH groups is a stabilizing effect. c. 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. d. Conformer B because the large OH groups are anti to each other.arrow_forward7. Circle those of which that are o,p-directors when attached to a benzene ringarrow_forward4.
