The reaction of R'-overset(O)overset(||...

The reaction of `R'-overset(O)overset(||)(C)-Cl` with `R_2 CuLi` or `R_2 Cd` gives a ketone, but with `RMgX` it gives a `3^@` alcohol.
(a) Explain why `RMgX` reaction does not give ketone.
(b) Account for the difference in behaviour of `RMgX` and `R_2 CuLi` or `R_2 Cd`.
( c) What is the relationship between the reactivity of the organometallic compound and activity of the metal ?

The reaction of (R'-underset(O)underset(||)(C )-Cl) with (R_(2)Cd) or with (R_(2)CuLi) gives a ketone but with (RMgX) gives a 3^(@) alcohol (R_(2)R'COH) . Statement 2: (C-Mg) bond has more ionic character than (C-Cu) or (C-Cd) bond abd (R ) group in Grignard reagent is more like R^(overset(..)(ɵ)) and is much more reactive for nuleophilic addition reaction.
