Question

Consider following reaction sequence:
(M has a molecular mass of 60 g/mol.)

List-I contains questions related to reaction sequences given above and List-II contains their answers:

$\begin{array}{cc}\text{List - I}& \text{List - II}\\ \text{(I) The compound which answers carbylamines test}& \text{(P) E}\\ \text{positive and gives a yellow dye when treated}& \\ \text{with benzenediazonium chloride is:}& \\ \text{(II) The compound which answers Liebermann test}& \text{(Q) B}\\ \text{positive and gives orange dye when treated}& \\ \text{with benzenediazonium chloride and also gives a}& \\ \text{brown ppt with ceric ammonium nitrate is:}& \\ \text{(III) Which compound gives p-acetyl phenol}& \text{(R) G}\\ \text{when treated with}AlC{l}_3\text{at room temperature?}& \\ \text{(IV) Which compound is used as a negative}& \text{(S) M}\\ \text{catalyst in the decomposition of}{H}_2{O}_2?& \\ & \text{(T) F}\\ & \text{(U) D}\end{array}$

Which of the following options has the correct combination considering List-I and List-II?

• A. $\left(I\right),\left(S\right)$ and $\left(III\right),\left(U\right)$
• B. $\left(II\right),\left(T\right)$ and $\left(I\right),\left(R\right)$
• C. $\left(IV\right),\left(U\right)$ and $\left(II\right),\left(R\right)$
• D. $\left(I\right),\left(R\right)$ and $\left(III\right),\left(P\right)$

Answer 1

The correct option is C $\left(IV\right),\left(U\right)$ and $\left(II\right),\left(R\right)$


(II) Compound G is phenol which gives positive Liebermann's nitroso test. Phenol reacts with benzenediazonium salt to produce a yellow-orange, azo compound. Unsubstituted phenol reacts with CAN to give a dark brown ppt, which helps in distinguishing it from alcohols.

(IV) Compound D is acetanilide which is used to decrease the rate of decomposition of $H_2{O}_2$.
