Define the term Branched chain hydrocarbons

Assertion (A): Pentane and 3 methyl pentane are chain isomers. Reason (R ): Pentane is a straight-chain alkane while 3 -methyl pentane is branched-chain alkane.

Assertion (A) : Pentane and 2-methy1 pentane are homolo-gues. Reason (R ) : Pentane is a straight-chain alkane, while 2-methy1 pentane is a branched-chain alkane.

Assertion : Butane and 2-methylbutane are homologues. Reason : Butane is a straight chain alkene while 2-methylbutane is a branched chain alkene.
