Question

are alkanes, alkenes, alkynes functional groups. give reason

Answer 1

A functional group is a portion of a molecule that is a recognizable/classified group of bound atoms. In organic chemistry it is very common to see molecules comprised mainly of a carbon backbone with functional groups attached to the chain.


The definition of functional groups itself says that the portion of a molecule that is recognizable is a functional group
and we can recognise an alkane, alkene and alkyne so yes they are functional groups.
