Question

the stereoisomers formed due to restricted rotation about the double bond are called​

Answer 1

Answer:

Cis–trans and E-Z isomerism

Stereoisomerism about double bonds arises because rotation about the double bond is restricted, keeping the substituents fixed relative to each other. ... The simplest examples of cis-trans isomerism are the 1,2-disubstituted ethenes, like the dichloroethene (C2H2Cl2) isomers shown below.
