List of top Chemistry Questions on Chemical Reactions of Haloalkanes and Haloarenes asked in JEE Main

$\textbf{The orange colour of } \text{K}_2\text{Cr}_2\text{O}_7 \textbf{ and purple colour of KMnO}_4 \textbf{ is due to}$

Statement I: High concentration of strong nucleophilic reagent with secondary alkyl halides which do not have bulky substituents will follow \(S_N2\) mechanism.

Statement II: A secondary alkyl halide when treated with a large excess of ethanol follows \(S_N1\) mechanism.

In the light of the above statements, choose the most appropriate from the questions given below:

$\textbf{A and B formed in the following reactions are:}$ \[ \text{CrO}_2\text{Cl}_2 + 4\text{NaOH} \rightarrow \text{A} + 2\text{NaCl} + 2\text{H}_2\text{O} \] \[ \text{A} + 2\text{HCl} + 2\text{H}_2\text{O}_2 \rightarrow \text{B} + 3\text{H}_2\text{O} \]
