प्रश्न
Write the names and formulae for the first three members of the homologous series for chloroalkanes.
उत्तर
The general formula of chloroalkanes (haloalkanes) is CnH2n+1-X (where, X is Cl, Br or I).
Therefore, the first three members of the chloroalkane series will be:
Chloromethane (CH3Cl)
Chloroethane (C2H5Cl)
Chloropropane (C3H7Cl)
