List of top Chemistry Questions on Chemical Reactions of Haloalkanes and Haloarenes

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

The correct IUPAC name of (CH₃)₃C-CH₂Br is:

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:

$\textbf{A and B formed in the following reactions are:}$ \[ \text{CrO}_2\text{Cl}_2 + 4\text{NaOH} \rightarrow \text{A} + 2\text{NaCl} + 2\text{H}_2\text{O} \] \[ \text{A} + 2\text{HCl} + 2\text{H}_2\text{O}_2 \rightarrow \text{B} + 3\text{H}_2\text{O} \]
Find out sum of the coefficients of all the species involved in the balanced equation: \(2MnO_4+I^-\xrightarrow[{Medium}]{Alkaline}\)

The major products ' A ' and ' B ', respectively, are

An organic compound $[ A ]\left( C _4 H _{11} N \right)$, shows optical activity and gives $N _2$ gas on treatment with The structure of $A$ is :

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Hydrolysis of an alkyl chloride is a slow reaction but in the presence of NaI, the rate of the hydrolysis increases
Reason R: $\,I ^{-}$is a good nucleophile as well as a good leaving group
