Options
- A. 12
- B. 24
- C. 28
- D. 36
Answer
C. 28
Step-by-step solution
Successive members of a homologous series differ by a -CH_2- group. The molar mass of a -CH_2- group is 12 + 2 1 = 14 g/mol . The difference between the second and fourth members of a homologous series corresponds to two -CH_2- groups. Difference in molar mass = 2 14 = 28 g/mol .
