Question

How many isomers of the following hydrocarbons are possible?
(a) C₃H₈
(b) C₄H₁₀

Answer 1

Compounds that have the same molecular formula but differ in their structural formula are called isomers.

(a) There is only one possible structure for C₃H₈. Hence, it has only one isomer.

(b) C₄H₁₀ has the following possible structures:

Hence, C₄H₁₀ has two possible isomers.
