Question: Chloroform can be obtained from....

Chloroform can be obtained from.

A

Methanol

B

Methanal

C

Propanol-1

D

Propanol-2

Answer

Propanol-2

Explanation

Solution

CaOCl2+H2O→Ca(OH)2+Cl2CaOCl_{2} + H_{2}O \rightarrow Ca(OH)_{2} + Cl_{2}

CH3−CH∣OH−CH3+Cl22-propanol→CH3−C∣∣O−CH3+2HCl\underset{\text{2-propanol}}{CH_{3} - \underset{\underset{OH}{|}}{CH} - CH_{3} + Cl_{2}} \rightarrow CH_{3} - \underset{\underset{O}{||}}{C} - CH_{3} + 2HCl

CH3−C∣∣O−CH3+3Cl2→CCl3−CO−CH3+3HClCH_{3} - \underset{\underset{O}{||}}{C} - CH_{3} + 3Cl_{2} \rightarrow CCl_{3} - CO - CH_{3} + 3HCl
