While of the following compounds will exhibit geometrical (or cis-trans) isomerism?  (i) `CH_(3)CH=CHCH_(2)CH_(3)` (ii) `C_(6)H_(5)CH=CHCH_(3)`  (iii) `CH_(2)=C(CH_(3))_(2)` `(CH_(3))_(2)C=CH-C_(2)H_(5)` Strategy: Essential requirement for any alkene to exhibit geometrical isomerism is that each of the double bonded carbon atoms should be attached to two different atoms or groups of atoms: img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/RS_P1_CHM_C17_S01_002_Q01.png" width="80%" `m!=n and p!=r`. Notice that `m` and `p` may be same or different Similarly, `n and r` may be same or different
