By how many -CH(2)- (methylene) units do...

By how many `-CH_(2)-` (methylene) units do the formulae of the first two members of homologous series of alkanes, methane `(CH_(4))` and ethane `(C_(2)H_(6))` differ? Similarly, by how many `-CH_(2)-` units do the neighbouring members ethane `(C_(2)H_(6))` and propane `(C_(3)H_(8))` differ from each other ?

Text Solution

Verified by Experts

The first two members of homologous series of alkanes, methane `(CH_(4))` and ethane `(C_(2)H_(6))` differ by one `-CH_(2)-` unit in their formulae. Similarly, ethane `(C_(2)H_(6))` and propane `(C_(3)H_(8))` differ by one `-CH_(2)-` unit from each other.
