(a) 1 - phenyl - 2 - butene 

(b) 3 - phenyl - 1 -butene 

(c) 2 - phenyl - 1 - butene 

(d) 1,1 - diphenyl - 1 - propene

Answer 1

The correct option (a) 1 - phenyl - 2 - butene

Explanation:

exhibits the phenomenon of geometrical isomerism due to C_ab = C_ad structure, so its two isomers are possible which are given as follow
