D.P. GUPTA, Preetima Bajpai and, Sanjeev Kumar Jha Solutions for Chapter: Organic Nitrogen Containing Compounds, Exercise 2: Exercise 2

An organic compound $\left(\mathrm{A}\right)$, on reduction, gives compound $\left(\mathrm{B}\right). \left(\mathrm{B}\right)$ on treatment with ${\mathrm{CHCl}}_3$ and alcoholic $\mathrm{KOH}$ gives $\left(\mathrm{C}\right). \left(\mathrm{C}\right)$ on catalytic reduction gives $\mathrm{N}-$methylaniline. What is compound $\mathrm{A}$?

A compound $\mathrm{A}$ has the molecular formula ${\mathrm{C}}_7{\mathrm{H}}_7\mathrm{NO}.$ On treatment with ${\mathrm{Br}}_2$ and $\mathrm{KOH}$, $\mathrm{A}$ gives an amine $\mathrm{B}$, which gives the carbylamine test. $\mathrm{B}$ upon diazotisation and coupling with phenol gives an azo dye. $\mathrm{A}$ can be
