Question

what is geometrical isomerism???

Answer 1

Cis–trans isomerism, also known as geometric 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

the compounds which possesses same structural formula but differ in the Spatial arrangement of atoms are groups about the double bond or a cyclic system called as a geometrical isomerism.
and this phenomenon is known as geometrical isomerism the cause of geometrical isomerism is due to restricted rotation about carbon carbon double bond of alkenes or about a sigma bond of cyclic compounds in which each carbon atom is bonded with two different substance a few examples are :
$cis \: but - 2 - ene \: \\ trans \: but - 2 - ene \:$
