Which of the following complex molecules possess the necessary restricted rotation and substituent a — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

1-Chloro-1-propene ($Cl-CH=CH-CH_3$) has different groups (Cl/H and H/Me) on both $sp^2$ carbons. Acetophenone oxime ($Ph-C(CH_3)=N-OH$) features a $C=N$ bond where the carbon is attached to a Phenyl and Methyl (different), and the nitrogen has an $-OH$ and a lone pair (different), showing GI. 1,1-Diphenyl-1-propene and Acetone oxime both have identical groups on one terminal end.
