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.

In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
