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

Options

  1. AThe members of the series are isomers of each other
  2. BThe members of the series have similar chemical properties
  3. CThe members of the series have the general formula C n H 2 n + 2 , where n is an integer
  4. DThe difference between any two successive members of the series corresponds to 14 unit of relative atomic mass

Correct answer

A. The members of the series are isomers of each other

Step-by-step solution

The difference between any two successive members of the homologous series - C H 2 - i.e., the molecular weight of every two adjacent members differ by 14. ( C H 2 = 12 + 2 = 14 )
