Chemistry - Halogen Derivative Question with Solution | TestHub

(A) $1^{\circ }$ amines give a bad smelling compound, called carbylamine, with alcoholic $\mathrm{KOH}$ and ${\mathrm{CHCl}}_3$. The reaction is called carbylamine reaction. $$\begin{array}{rl}& {\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{NH}}_2\stackrel{{\mathrm{CHCl}}_3+\text{ alc }\mathrm{KOH}}{⟶}\\ & {\mathrm{CH}}_3{\left({\mathrm{CH}}_2\right)}_3\mathrm{NC}\\ & \text{ bad smelling }\\ & \end{array}$$ (B) Terminal alkynes like ${\mathrm{CH}}_3\mathrm{C}\equiv \mathrm{CH}$ give white precipitate with ammoniacal ${\mathrm{AgNO}}_3$. $$\begin{array}{r}{\mathrm{CH}}_3\mathrm{C}\equiv \mathrm{CH}+{\mathrm{AgNO}}_3+{\mathrm{NH}}_4\mathrm{OH}⟶\\ {\mathrm{CH}}_3\mathrm{C}\equiv \mathrm{CAg}\\ \text{ white ppt }\end{array}$$ (C) Ester $\left({\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{COOCH}}_3\right)$ undergoes alkaline hydrolysis. $$\begin{array}{r}{\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{COOCH}}_3+\mathrm{NaOH}⟶\\ {\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{COONa}+{\mathrm{CH}}_3\mathrm{OH}\end{array}$$ (D) $2^{\circ }$ alcohols (the alcohols that have ${\mathrm{CH}}_3\mathrm{CHOH}$ - group) give cloudiness with Lucas reagent (anhy ${\mathrm{ZnCl}}_2+$ conc $\mathrm{HCl}$ ) within 5 minutes.
