Answer 1

Answer:

Any molecules or ions having same formulas but different shapes are called isomers. Two isomers of alkane which are found in LPG cylinders are  iso-butane and n-butane. Butane is an alkane, and is a gaseous organic compound. The number of carbon atom Butane has is 4.

The structural formulas of iso-butane and n-butane which are in condensed state are given below as follows:
