Q.
$C_{2}$ is rotated anticlockwise 102${^\circ}$C about $C_{2} - C_{3}$ bond. The resulting conformer is
A) Partially eclipsed
B) Eclipsed
C) gauche
D) Staggered
Explanation
(c)
[image:12_image432.emf]Here, when $C_{2}$ is rotated anticlockwise 120${^\circ}$ about $C_{2} - C_{3}$ bond the resulting conformer is $Gauche\$conformer.
Hence,
