Chemistry - Carbonyl compounds Question with Solution | TestHub

The substrate has three Grignard-reactive sites: the –SH proton (1 eq, acid-base reaction), the ketone C=O (1 eq, addition installs a CH₃ that becomes C–OH after H₃O⁺), and the –CH₂Cl group (1 eq, coupling converts CH₂Cl into CH₂CH₃).

The major product shown therefore needs $x=3$ equivalents of CH₃MgBr.

Answer (C).
