Question

Identify A, B, C and rewrite the chemical reactions:

$$\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CH}{\phantom{A}}_2\mathrm{Cl}+\mathrm{KOH}{\phantom{A}}_{(\mathrm{aq})}\stackrel{\mathrm{\Delta }}{\to }{\phantom{A}}_{\phantom{}}^{\phantom{\prime }}{\phantom{A}}_{\phantom{2}}^{\phantom{2}\prime }\mathrm{A}{\phantom{A}}^{\prime }\underset{\mathrm{powder}}{\overset{\mathrm{hot}\mathrm{Cu}}{\to }}{\phantom{A}}_{\phantom{}}^{\phantom{\prime }}{\phantom{A}}_{\phantom{2}}^{\phantom{2}\prime }\mathrm{B}{\phantom{A}}^{\prime }\underset{\mathrm{dil}\mathrm{H}{\phantom{A}}_2\mathrm{SO}{\phantom{A}}_4}{\overset{\mathrm{K}{\phantom{A}}_2\mathrm{Cr}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_7}{\to }}{\phantom{A}}_{\phantom{}}^{\phantom{\prime }}{\phantom{A}}_{\phantom{2}}^{\phantom{2}\prime }\mathrm{C}{\phantom{A}}^{\prime }$$

Answer 1

$$\underset{\mathrm{Ethyl}\mathrm{chloride}}{\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CH}{\phantom{A}}_2\mathrm{Cl}}+\underset{\mathrm{hydroxide}}{\underset{\mathrm{Potassium}}{\mathrm{KOH}}}{\phantom{A}}_{(\mathrm{aq})}\stackrel{\mathrm{\Delta }}{\to }\underset{\mathrm{Ethonol}}{\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CH}{\phantom{A}}_2\mathrm{OH}}\underset{\mathrm{powder}}{\overset{\mathrm{hot}\mathrm{Cu}}{\to }}\underset{\mathrm{Ethanal}}{\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{CHO}}\underset{\mathrm{dil}\mathrm{H}{\phantom{A}}_2\mathrm{SO}{\phantom{A}}_4}{\overset{\mathrm{K}{\phantom{A}}_2\mathrm{Cr}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_7}{\to }}\underset{\mathrm{Ethanoic}\mathrm{acid}}{\mathrm{H}{\phantom{A}}_3\mathrm{C}-\mathrm{COOH}}$$

Where,

A: ${\displaystyle H_{3}C-C{H}_{2}OH}$ (Ethonol)

B: ${\displaystyle C{H}_3-CHO}$ (Ethanal)

C: ${\displaystyle C{H}_3-COOH}$ (Ethanoic acid)
