Grignard reagent: R-X + Mg in dry ether gives:
AR-OH
BR-Mg-X (organomagnesium halide; powerful nucleophile/base)
CR-Cl
DNo reaction
Answer & Solution
Correct answer: B. R-Mg-X (organomagnesium halide; powerful nucleophile/base)
Grignard reagent: R-MgX. Forms in dry ether. Carbon is δ-, magnesium δ+. Acts as carbanion equivalent. Reacts with H₂O (destroys reagent: → R-H), CO₂ (→ RCOOH), carbonyls (→ alcohols).
