n-pentane and neopentane are:

Give the names n-pentane, and Neo-pentane to the above structrual formulae.

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 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-methyl pentane are homologous. Reason (R ) : Pentane is a straight-chain alkane, while 2-methyl pentane is a branched-chain alkane.
