What is the numerical difference in molar masses of second and third member of a homologous series?

  • Correct answer
    A
    14
  • B
    12
  • C
    10
  • D
    2

Solution

Two successive homologues differ by one $-\mathrm{CH}_2$ (methylene) unit (i.e., molecular weight of each successive member differs by 14 units).

Hence, the correct answer is option: 'A'.
