Question

Nomenclature of unsaturated hydrocarbon ​

Answer 1

The simplest alkenes are ethene (traditionally called ethylene), C2H4 or CH2=CH2, and propene (or propylene), C3H6 or CH3CH=CH2 (part (a) in the figure below). The names of alkenes that have more than three carbon atoms use the same stems as the names of the alkanes (see table above, “The First 10 Straight-Chain Alkanes”) but end in –ene instead of –ane.

Answer 2

Answer:

Alkanes contain only carbon–hydrogen and carbon–carbon single bonds, alkenes contain at least one carbon–carbon double bond, and alkynes contain one or more carbon–carbon triple bonds.
