Concept explainers
Interpretation: The expected potential-energy diagram for the rotation about the bond in should be drawn along with Newman projections of each staggered and eclipsed conformation.
Concept introduction: Various interconvertible forms that results from rotation around the bond in ethane are termed as conformer. To depict such conformation Newman projections are written. These are obtained by conversion of hashed-wedged line structure simply when molecule is viewed in a plane along the as illustrated below:
Thus in Newman projection of simple ethane molecule the “front” is depicted as intersection of three bonds with three attachedThe other three bonds connect to the large circle corresponding to “back” carbon in bond.

Explain your answer literally step by step.arrow_forwardDraw 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. H₂C OH C₂ HO CH3 Which of the following is the most stable staggered conformer? Me Me *** Conformer B Me- Me Conformer A Me 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.arrow_forwardConsider 1-bromopropane, CH3CH2CH2Br.
