Which of the following will have least hindered rotation about carbon-carbon bond? (a) Ethane (b) Ethylene(c) Acetylene (d) Hexachloroethane

Answers

Answered by Anonymous

In ethylene there is restricted rotation where as in accetylene there is no rotation.Hexachloromethane has more rotation than ethylene but less than ethane because of larger size of chlorine atoms present in it than those of hydrogen atoms in ethane.

Hence (a) is the correct option

Answered by Anonymous

a) Ethane is right now, because they are sp3 hybridization and carrying single bond between C-C.
