Detailed Solution

As we all know butane is an alkane and is the general formula for Alkanes. S structural isomers are produced by butane. These isomers have various structural formulae but have a similar molecular formula.

Structure-wise, butane exhibits isomerism. Chain isomerism is the word used to describe the phenomena where compounds with the same molecular formula but a distinct arrangement of carbon chains within the molecule are referred to as chain isomers or skeletal isomers.
The formula of Butane isomer is:
The structural formulae of the two isomers of butane are-
n-butane or butane:
2-methyl propane or isopropane-

Hence, the correct answer is option B.
