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
CH3COOH+PCl5 \(\rightarrow\) A \(\xrightarrow[Anh.\,AlCl_3]{C_6H_6}\) B \(\xrightarrow[ether]{C2H5MgBr}\) ‘C’, product C would be
CH3CH(OH)C2H5
CH3COC6H5
CH3CH(OH)C6H5
The Correct Option is D
Solution and Explanation
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.
