Q.
Geometrical isomerism is not shown by
Organic Chemistry – Some Basic Principles and Techniques
Solution:
A compound containing a double bond can show geometrical isomerism only when identical groups are not present on the double bonded carbon. $1,1-$dichloro-$1$-pentene, i.e.
cannot show geometrical isomerism because on $C-l $ identical groups ($Cl$ ) are present.
