CONFORMATIONAL ISOMERISM:
The different molecular arrangements arising as a result of rotation around carbon carbon single bonds are called conformational isomers or rotational isomers and the phenomenon is called conformational isomerism.
Numerous possible arrangements of ethane are possible. Two extreme conformations are known. These are eclipsed conformation and staggered conformation.

Alkenes Unsaturated hydrocarbon which have double bond. General molecular formula CnH2n
C – C bond hybridization 1.34 A 0 sp 2 hybridization When we treated Alkene with chlorine, oily products are obtained. So Alkenes are also known as Olefins.( Greek olefiant meaning oil forming). Show chain, positional and geometrical isomerism
