Write the molecular formula of first two members of homologous series having functional group -Cl.
Advertisements
Solution
The general formula for the homologous series of functional group −Cl is CnH2n+1Cl.
The two consecutive members of this series are:
a. CH3Cl (Chloromethane)
b. CH3CH2Cl (Chloroethane)
where n is 1 and 2 respectively
The molecular formula for both of them are CH3Cl and C2H5Cl.
