answer is 3. geometrical isomers are cis and trans. similar group(s) should be present on either side of c=c.
only in 2-chloro propene the first carbon has 2 H while the other C attached to = has no H for geometrical isomer.
not necessary that H should be present but both Carbon having = should have atleast one same group attached.did u understand?
