Question

which type of isomerism is possible in CH3 Ch CH3 CH3​

Answer 1

Answer:

Sterioisomer is possible

Answer 2

Answer : This is a geometrical isomerism or cis-trans isomerism.

Explanation :

The configuration of the geometrical isomers is designated by two system which are, Cis-trans system.

The rules for Cis-trans system are :

The atoms or groups attached to each olefinic carbon are given priority as per the sequence rule.

• If the higher priority groups are present on same sides across the double bond, the geometrical isomer is said to have 'cis' configuration.
• If the higher priority groups are present on opposite sides across the double bond, the geometrical isomer is said to have 'trans' configuration.

In the given compound, higher priority group is $CH_3$.

When both $CH_3$ groups are present on same sides across the double bond, the geometrical isomer is said to have 'cis'.

When both $CH_3$ groups are present on opposite sides across the double bond, the geometrical isomer is said to have 'trans'.

Hence, this is a geometrical isomerism or cis-trans isomerism.
