MCQ
The hydrocarbon 2-methyl butane is an isomer of:
  • A
    n-butane
  • B
    n-pentane
  • C
    Propane
  • D
    None of these

Answer

(b) $n$-pentane
Explanation: The hydrocarbon 2-methylbutane is an isomer of $n$-pentane. The structural difference between the two isomers lies in the arrangement of carbon atoms in the carbon chain. 2-methylbutane has a branched structure with a methyl group $\left( CH _3\right)$ attached to one of the carbon atoms, while $n$-pentane is a straight-chain hydrocarbon consisting of five carbon atoms in a row.
