Which ones are dihalogen derivatives of alkanes?
a, b only
a, b and d only
b only
a,b and c only
Dihalogen derivatives of hydrocarbons contain two halogen atoms apart from carbon and hydrogen
Here, in
It is Dihalogen derivatives of alkene not alkane.
In (c) Hydrogen is replaced from the alkane group, not from the Benzene group, so it is Dihalogen derivatives of alkane.
a,b and c are Dihalogen derivatives of alkene.
Therefore, option (4) is correct.
