Question

write a short note on geometrical isomerism​

Answer 1

cis-trans isomerism also called geometrical isomerism or configurational isomerism is a term used in organic chemistry. the prefixes 'cis' and 'trans' are from latin. 'this side of' and 'the other side of' respectively.

Answer 2

Geometrical isomerism is also called cis-trans isomerism .Two carbon joined by a single bond are capable of free rotation about it.however, two carbon atoms joined by double bond they cannot rotate freely.as a result the relative position of the various groups attached to these carbon atoms get fixed and gives rise to cis-trans isomerism.
