Vedclass · Answer

(A) Let us analyze each reaction:$A$: The reaction is a Wolff-Kishner reduction. It reduces a carbonyl group to a methylene group. The alkene double bond is unaffected. The product shown is correct.$B$: This is a Hofmann elimination reaction. It involves the thermal decomposition of a quaternary ammonium hydroxide to form an alkene. The product shown is correct.$C$: The reaction of a ketone with $PCl_5$ replaces the carbonyl oxygen with two chlorine atoms (gem-dichloride). The product shown is correct.$D$: The reaction $Ph-I \xrightarrow[\Delta]{Cu} Ph-Ph$ is an Ullmann coupling reaction. However,the Ullmann reaction typically requires an aryl halide (like iodobenzene) and copper powder to form a biaryl compound. The reactant $Ph-I$ is iodobenzene,and the product $Ph-Ph$ is biphenyl. This reaction is actually correct. Wait,re-evaluating the options: In option $A$,the starting material is a ketone with an alkene. Wolff-Kishner reduction $(N_2H_4, OH^-, \Delta)$ reduces the ketone to an alkane. The product shown in the image for $A$ is a ketone,which means the reaction did not occur as expected. Therefore,$A$ is the incorrect product.
