torsional strain is related to bond angle in relation to
rotation of bond and steric hinderence is related to the
size(bulky nature)of group attached and its effect on the
approaching group

Answer / p.kaviarasan

bond angle difference is there.steric hindrence would
increase the bond angle.but bond angle decreases with
increase in torsional strain.

for example,smaller cyclic compounds having larger strain.
ex:cyclopropane

Larger cyclic compounds having smaller strain.
ex: cyclohexane

Why don't electrons repel each other during the formation of bond?????????
