Among the following oxime derivatives, which one will fundamentally FAIL to exhibit geometrical isom — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Geometrical isomerism in oximes ($>C=N-OH$) requires that the central $sp^2$ hybridized carbon atom be attached to two *different* alkyl or aryl groups. Acetone oxime is derived from the symmetrical ketone acetone ($CH_3-CO-CH_3$), meaning the carbon is attached to two identical methyl groups, rendering it incapable of showing GI.
