Question

In a set of the given reactions, acetic acid yielded a product C.
CH₃COOH+PCl₅ \(\rightarrow\) A  \(\xrightarrow[Anh.\,AlCl_3]{C_6H_6}\) B  \(\xrightarrow[ether]{C2H5MgBr}\)  ‘C’, product C would be 

• A. CH₃CH(OH)C₂H₅
• B. CH₃COC₆H₅
• C. CH₃CH(OH)C₆H₅
• D.

Answer 1

The Correct Option is D

When carboxylic acids react with PCl₅, they form acid chlorides. These acid chlorides, when reacted with benzene or its derivatives, result in the formation of ketones. This chemical transformation is commonly referred to as Friedel-Crafts acylation, and it is typically carried out in the presence of anhydrous AlCl₃. Subsequently, ketones, when subjected to reactions with Grignard reagents, lead to the synthesis of tertiary alcohols.
