Grignard reagent does not show reaction with

Solution (By Examveda Team)

Option A: alkoxyalkanes
This option suggests that Grignard reagent does not show a reaction with alkoxyalkanes. This statement is correct. Alkoxyalkanes (ethers) are generally inert to Grignard reagents because they do not have active hydrogen atoms or functional groups that can react with the Grignard reagent.

Option B: alkanones
This option suggests that Grignard reagent does not show a reaction with alkanones. This statement is incorrect. Alkanones (ketones) react readily with Grignard reagents to form tertiary alcohols after hydrolysis.

Option C: alkylakantotes
This option suggests that Grignard reagent does not show a reaction with alkylakantotes. This statement is incorrect. It appears there may be a typographical error in the term "alkylakantotes" as it is not a recognized chemical term. Assuming the intended term is something like alkyl alkanoates (esters), Grignard reagents react with esters to form tertiary alcohols after hydrolysis.

Option D: acyl halides
This option suggests that Grignard reagent does not show a reaction with acyl halides. This statement is incorrect. Acyl halides (acid chlorides) react with Grignard reagents to form tertiary alcohols after two equivalents of the Grignard reagent are added and followed by hydrolysis.

Conclusion:
The correct answer is Option A: alkoxyalkanes because Grignard reagents do not show a reaction with ethers, as ethers lack the reactive functional groups or active hydrogen atoms needed to engage in a reaction with Grignard reagents.
