Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Total correct compounds = 4 (structures iii, iv, v, and vii).

(iii) & (iv): Show GI because the exocyclic double bond carbon has two different groups (–H and –CH₃), and the ring pathways are unsymmetrical due to the substituents.

(v) & (vii): Show GI because they contain disubstituted sp³ ring carbons with two different groups (–H and –CH₃), enabling cis/trans isomerism.

Others (i, ii, vi, viii): Do not show GI due to identical groups attached to the double bond/ring carbons, or because allene (vi) has an even number of cumulative double bonds (making groups perpendicular).
