NEETChemistrySome Basic Concepts of Organic ChemistryMCQ+4 / −1
The correct statement regarding the comparison of staggered and eclipsed conformations of ethane, is
  1. A
    the eclipsed conformation of ethane is more stable than staggered conformation even through the eclipsed conformation has torsional strain
  2. B
    the staggered conformation of ethane is more stable than eclipsed conformation, because staggered conformation has no torsional strain
  3. C
    the staggered conformation of ethane is less stable than eclipsed conformation, because staggered conformation has torsional strain
  4. D
    the eclipsed conformation of ethane is more stable than stggered conformation, because eclipsed conformation has no torsional strain.

Correct answer: B

NEET 2016 Phase 1 Chemistry - Some Basic Concepts of Organic Chemistry Question 51 English Explanation

In staggered conformation any two hydrogen atoms on adjacent carbon atoms are as far apart as possible there by minimising repulsion between the electron clouds $\sigma $- of bonds of two non-bonded H-atomic (torsional strain)
