A compound containing a double bond can show geometrical isomerism only when identical groups are not present on the double bonded carbon.

Q. The compounds show the geometrical isomerism are : (2) CH3​CH2​−CH=CH−CH3​ (3) Br2​C=CH2​ (4) ClHC=CHCl

1, 2 and 3 are correct

1 and 2 are correct

2 and 4 are correct
