Physical properties. ... Preparation of alkenes. ... Reactions. ... Summary. ...
General formula for Alkane is CnH(2n+2) ; n is integer, n= 1, 2, 3…. For alkene it is CnH(2n) ; n = 2, 3, 4… For alkyne it is CnH(2n-2) ; n = 2,3,4… Since, alkene and alkynes refers to double bonded carbons & tripple bonded carbons respectively, there must be at least 2 carbon atoms.
Alkenes are acyclic (branched or unbranched) hydrocarbons having one carbon-to-carbon double bond (C=C) and the general molecular formula CnH2n . Because alkenes contain less than the maximum possible number of hydrogen atoms per carbon atom, they are said to be unsaturated.

Alkynes have one or more carbon-carbon triple bonds. Alkenes and alkynes are called as unsaturated hydrocarbons.
Double bonds in hydrocarbons are indicated by replacing the suffix -ane with -ene. If there is more than one double bond, the suffix is expanded to include a prefix that indicates the number of double bonds present (-adiene, -atriene, etc.). Triple bonds are named in a similar way using the suffix -yne.
Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. ... Alkanes are also saturated hydrocarbons. Alkanes are the simplest and least reactive hydrocarbon species containing only carbons and hydrogens.
