Question

What is the functional group of alkane and alkene?

Answer 1

carbon -carbon bond

Explanation:

In alkane, actually no functional group is present. But, sometimes it is considered that carbon - carbon single bond is the functional group of alkane.

In alkene, carbon = carbon double bond is the functional group. In any reaction , the bond is broken and new bond is created .As a result, a new compound is formed . So, carbon = carbon double bond is the desired functional group present in alkene .
