Which among the following is substitution reaction ?

Which among the following is substitution reaction ?
  1. $\mathrm{R}_{3} \mathrm{COH} \xrightarrow[\text { Conc. } \mathrm{HCl}]{\text { Anhy. } \mathrm{ZnCl}_{2}}$ Turbidity
  2. All of these

Solution

$\mathrm{R}_{3} \mathrm{COH} \frac{\text { Anhy. } \mathrm{ZnCl}_{2}}{\text { Conc. HCl }} \mathrm{R}_{3} \mathrm{C} . \mathrm{Cl}$ It is substitution reaction. $\mathrm{R}_{3} \mathrm{C} . \mathrm{Cl}$ being insoluble in $\mathrm{H}_{2} \mathrm{O}$ give turbid solution.
