Which of the statements are about the following reaction ?

Options

A. Ketones are more reactive than RCOCl, therefore ketones further react with RMgX to give `3^(@)` alcohols.
B. `(C-Mg)` bond is more ionic than `(C-Cu)` or `(C-Cd)` bond.
C. Nucleophile `R^(overset(..)(Θ))` from Grignard reagent is more reactive and the reaction of RMgX with RCOCl is a nucleophilic addition reaction.
D. Cu or Cd forms complex with Cl of RCOCl, `[R-overset(delta+)underset(O)underset(||)C...Cl...overset(delta-)CdR_(2)]`, similar to acylium-like ion with greater `(delta+)` charge on C, which bonds even with the weakly nucleophilic R of `R_(2)Cd` or `R_(2)CuLi`.

Answer

A, B, C, D
