232131 The isomerism that arises due to restricted bond rotation is
The isomerism which arises due to restricted bond rotation is called geometrical isomerism Example.
232132 Dihedral angle between two methyl groups of n-butane in the gauche and anti forms are
(C): Dihedral angle between two methyl groups in n-butane is 60∘ and 180∘ in gauche and anti form.
232133 Stereoisomers differ in
Stereoisomer differ in configuration. In stereoisomer having same molecular formula same connectivity but differ in configuration.
232134 Maleic acid and Fumaric acids are
Maleic acid \& fumaric acid are both of the geometric isomers. Maleic acid is the cis isomer \& fumaric is the trans-isomer.
