Question

The molecular formula of a homologue of butane is: [ ]

A) C₄H₈ B) C₃H₆ C) C₄H₆ D) C₃H₈​

Answer 1

C3H8 is the molecular formula of a homologue of butane as it satisfies the general formula CnH2n+2 of the alkane series.

Answer 2

Answer:

IN BUTANE THE MOLECULAR FORMULA IS C4H10 (CnH2n+2)(saturated hydrocarbon)

IN BUTENE THE MOLECULAR FORMULA IS C4H8

(CnH2n)(unsaturated hydrocarbon)

AND IN BUTYNE THE MOLECULAR FORMULA IS C4H6(CnH2n-2)(unsaturated hydrocarbon)

hope this hepls u
