Question

Which one of the following statements is incorrect, in case of homologous series of alkanes,

• A. The members of the series are isomers of each other
• B. The members of the series have similar chemical properties
• C. The members of the series have the general formula $C_{n}H_{2 n + 2}$ , where n is an integer
• D. The difference between any two successive members of the series corresponds to 14 unit of relative atomic mass

Answer 1

Answer: (A)

The difference between any two successive members of the homologous series $-CH_{2}-$ i.e., the molecular weight of every two adjacent members differ by 14.

$\left(\right.CH_{2}=\text{12}+2=\text{14}\left.\right)$
