Solution

The correct option is D

Both A and C


The explanation for correct answers:

Option (D)

  • A Grignard reagent is an organomagnesium compound and represented by the general formula R-Mg-X where R is an alkyl or aryl group and X is a halogen group.
  • Ethyl formate(C2H5COOH) reacts with Methyl magnesium bromide and produces Acetaldehyde.

C2H5COOHEthylformate+CH3MgBrMethylmagnesiumbromideCH3CHOAcetaldehyde

  • Hydrogen cyanideHCN reacts with Methyl magnesium bromide and produces Acetaldehyde.

HCNHydrogencyanide+CH3MgBrMethylmagnesiumbromideCH3CHOAcetaldehyde

  • Hence option (D) Both A and C is correct.

The explanation for incorrect answers:

Option (B) Ethyl acetate

  • Ethyl acetate (C2H5COOCH3) reacts with Grignard reagent and produces Ketone.

C2H5COOCH3Ethylacetate+CH3MgBrMethylmagnesiumbromideCH3COCH3Acetone

  • Hence option (B) Ethyl acetate is incorrect

Therefore, option (D) is the correct answer.
