Question

Hex-2-ene and 2-methylpent-2-ene exhibit
a) chain isomerism
b) position isomerism
c) geometrical isomerism
d) optical isomerism.

Answer 1

Answer ⇒ Option (a). Chain Isomers.

Explanation ⇒ The Given compounds are not the Geometrical Isomers, because there is no Streo-centre in them.

But they are the Chain Isomers because there is the Change in length of the Carbon chain.

Hence, Option (a) is correct.

These Given compounds are not the Optical Isomers because for the compounds to be optically isomers, means  ENANTIOMERS.

But the Given compounds are not the mirror image of each other, thus, they are not ENANTIOMERS, means Optical Isomers.

Hope it helps.

Answer 2

Answer ⇒ Option (a). Chain Isomers.

Explanation ⇒ The Given compounds are not the Geometrical Isomers, because there is no Streo-centre in them.

But they are the Chain Isomers because there is the Change in length of the Carbon chain.

Hence, Option (a) is correct.

These Given compounds are not the Optical Isomers because for the compounds to be optically isomers, means  ENANTIOMERS.
