Question

In alkenes do we onky check the double bond between carbon and carbon only

Answer 1

Yes in Alkanes a double bond is formed only between 2 carbon atoms.

Answer 2

In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond. The words alkene and olefin are often used interchangeably . Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula CnH2n.
