The aldehydes which will not form Grignard product with one equivalent of Grignard reagents are
(A)( A ) The aldehydes which will not form Grignard product with one equivalent of Grignard reagents are ( A ) ( B ) (C) ( D )

(B)( B ) The aldehydes which will not form Grignard product with one equivalent of Grignard reagents are ( A ) ( B ) (C) ( D )

(C)\left(C\right) The aldehydes which will not form Grignard product with one equivalent of Grignard reagents are ( A ) ( B ) (C) ( D )

(D)( D ) The aldehydes which will not form Grignard product with one equivalent of Grignard reagents are ( A ) ( B ) (C) ( D )

Options

  1. A(B),(C)\left(B\right), \left(C\right)
  2. B(B),(C),(D)\left(B\right), \left(C\right), \left(D\right)
  3. C(C),(D)\left(C\right), \left(D\right)
  4. D(B),(D)\left(B\right), \left(D\right)

Correct answer

D. (B),(D)\left(B\right), \left(D\right)

Step-by-step solution

BandDBandD have active hydrogen (acidic hydrogen). So, acid base reaction will take place with Grignard reagent.
