Which of the following statements is//are correct ?

Options

A. When `G.R` reaction with alkyl isocyanide, of electrophile `(overset(oplus) MgX)` first adds of the `C` atom of `(overset(oplus) N -= overset(Ө) C)` group and then the nucleophile `(R^(Ӫ))` adds of the same `C` atom.
B. When `G.R` reacts with alkyl isocyanide, the nucleophile `(R^(Ӫ))` first adds to the `C` atom of `(overset(oplus) N -= overset(Ө) C)` group and then the electrophile `(overset(oplus) MgX)` adds to the same `C` atom.
C. When `G.R` reacts with alkyl isocyanide, electrophile `(overset(oplus) MgX)` adds to the `C` atom of `(-overset(oplus) N -= overset(Ө) C)` group and the nucleophile `(R^(Ӫ))` adds of the `N` atom.
D. when alkyl isocyanide is hydrolysed in dilute acidic medium. `H^(oplus)` (electrophile) adds to the `C` atom of `(-overset(oplus) N -= overset(Ө) C)` group and then `overset (Ө) O H` (nuclephile) adds to the same `C` atom.

Answer

A, B

Explanation

(a,d) In an isocyanide, first an electrophile and then a nucleophile is added at the same `C` atom of `(-overset(oplus) N -= overset (Ө)C)` group to form a species which usually undergoes further transformations.
As explained above.
