Q13 / 150 · MHT CET 2020 (15 Oct Shift 2) · Chemistry

Identify 'A' in the following reaction $$ \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{HCl} \stackrel{\mathrm{A}}{\longrightarrow} \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Cl}+\mathrm{H}_{2} \mathrm{O} $$

  • Correct answer
    A
    anhydrous $\mathrm{ZnCl}_{2}$
  • B
    pyridine
  • C
    conc. $\mathrm{H}_{2} \mathrm{SO}_{4}$
  • D
    $\mathrm{NaNO}_{2}$

Solution

$\mathrm{C}_{2} \mathrm{HSOH}+\mathrm{HCl} \stackrel{\mathrm{ZnCl}_{2}}{\longrightarrow} \mathrm{C}_{2} \mathrm{Hs} \mathrm{Cl}+\mathrm{H}_{2}$ (alcohol) ( Hhyd chloride) dehydrating agent $\mathrm{ZnCl}_{2}$ is used in the reaction.

Hence, the correct answer is option: 'A'.
