Reaction with HI and P

H2,Pd/BaSO4

One mole of C2H5MgBr.

Answer :

D

Solution :

CH3COCl+C2H5MgBr→2CH3COC2H5+Mg(Br)Cl

Explanation:

Answer 2

Reaction with one mole of ethyl grignard is the correct choice.

Explanation:

• The Acetyl chloride is the compound with formula CH3COCl.

• The reagent needed is the ethyl grignard.

• The ethyl grignard is a very good nucleophile which attaches the carbonyl carbon of Acetyl chloride.

• The intermediate formed is the tetrahedral intermediate.

• This then regenerates the double bond between the oxygen and carbon and the chloride leaves forming Magnesium bromide chloride.
