MCQ

Torsional strain in eclipsed conformations of a molecule is due to:

A
Repulsion between the eclipsed carbons.
B
Repulsion between aligned electron pairs of the eclipsed bond.
C
Repulsions betwen aligned ‘H’.
D
Repulsions between C-H bonds of eclipsed conformation.

✓

Answer

Repulsion between aligned electron pairs of the eclipsed bond.

Explanation:

The eclipsed bonds are parallel to each other facing repulsions due to aligned electron pairs in the bonds.
