Question

In which of the following compounds is geometrical isomerism possible ? (1) CH 2 =CH-CH 2 CH 3 (2) CH 3 O-CH=CH-COOCH 3 (3) BrCH 2 -CH=CH-CH 2 Cl

TestHub · Accepted Answer

Ans. (D). (1) But-1-ene has two H atoms on the terminal CH 2 carbon : no G.I. (2) CH 3 O-CH=CH-COOCH 3 : each double-bond carbon carries two different groups : G.I. possible. (3) BrCH 2 -CH=CH-CH 2 Cl : each double-bond carbon carries H and a CH 2 X group : G.I. possible.
