Alkane has the lowest van der walls force
|
|
|
The electronegativity of alkane is lower than alkene and alkyne
|
|
|
Alkane is not reactive
|
Detailed explanation-1: -Due to more attractive force the molecules come closer and volume becomes less. So the density increases.
Detailed explanation-2: -Density is inversely proportional to the volume occupied. Hence, the density of alkanes increases on increasing the no. of carbon atoms in alkanes.
Detailed explanation-3: -Alkenes and alkynes are unsaturated hydrocarbons with atleast one double bond which is a bond, whereas alkanes contain only bonds. As bonds are stronger than bonds, alkanes are less reactive than alkenes and alkynes.
Detailed explanation-4: -Alkanes have only single bonds between carbon atoms and are called saturated hydrocarbons. Alkenes have at least one carbon-carbon double bond. Alkynes have one or more carbon-carbon triple bonds. Alkenes and alkynes are called as unsaturated hydrocarbons.
