Question

In the given reaction, carbonyl compound (x) and Grignard reagent (y) can be.

A)

B)

C)

D)

Answer 1

In the product there is a formation of a new carbon-carbon bond also we know that the magnesium in the Grignard reagent is electropositive in nature and which makes the alkyl group a partially negative compound. Thus, involving a nucleophilic substitution in the reaction.

Complete step by step answer:
First, we know what Grignard Reaction is,
The reaction in which the addition of an organo magnesium halide to a ketone or aldehyde, to give a tertiary or secondary alcohol is called Grignard reaction. The Grignard reagent reacts with formaldehyde results in the formation of primary alcohol. Grignard Reagents also are utilized in the subsequent important reactions: The addition of a more than a Grignard reagent to an ester or lactones gives a tertiary alcohol during which two alkyl groups are an equivalent, and therefore the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone via a metallic imine intermediate.
The given reaction is written as,

There are three different R groups in the product, thus three different carbonyl compounds and three different Grignard reagents are used to obtain the product.

Therefore, the option A, B, and C is correct.

Note: We must remember that the Grignard reagent is used to polarize the bond between carbon and magnesium and it makes the reagent to act as a good nucleophile and strong base. Avoid the reactions with water because it reacts with water and forms alkanes so in order to avoid the formation of alkane’s diethyl ether is used as a solvent.
