MCQ
In the case homologous series of alkanes, which one of the following statements is incorrect
  • ✓
    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${C_n}{H_{2n + 2}}$,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

Correct option: A.
The members of the series are isomers of each other
a
(a) 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 $14$.

$(C{H_2} = 12 + 2 = 14)$
