Question
Write the molecular formula of first two members of homologous series having functional group −Br.
Solution
The general formula for the homologous series of functional group −Br is CnH2n+1Br.
The two consecutive members of this series are:
a. CH3Br(Bromomethane)
b. CH3CH2Br (Bromoethane)
where n is 1 and 2 respectively
The molecular formula for both of them are CH3Br and C2H5Br.
