Question

n-butane and isobutane are examples of :

• A. Chain isomers
• B. Geometrical isomers
• C. Position isomers
• D. Tautomers

Answer 1

The correct option is A Chain isomers

Isomers with different carbon skeleton (parent chain or side chain) are known as Chain isomers.
To find out chain isomers, First observe the principle carbon chain and then check the alkyl side chain.
Hence, n-butane and isobutane are examples of chain isomers.
