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 .
SAWHORSE REPRESENTATION
NEWMAN PROJECTION
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
