What is an alkene?

Answer 1

Apex- A hydrocarbon containing a carbon-carbon double bond

Answer 2

The compounds of hydrogen and carbon in which all the four valencies of the carbon are

not fully utilized and they contain a double bond are called alkenes.

For example : butene and ethene.

Alkenes are unsaturated hydrocarbons.

Answer 3

they are just like alkanes (single bonds) and alkenes (double bonds) except they have triple bonds.

so an alkyne is a unsaturated hydrocarbon with a triple carbon to carbon bond.

Answer 4

An alkene is an unsaturated, aliphatic hydrocarbon with one or more carbon-carbon double bonds.
