Question

how will you prepare chloroform from ethanol​

Answer 1

Answer:

Chloroform. is prepared in the laboratory by heating a mixture of Bleaching powder with ethanol or acetone. In this reaction, bleaching powder acts as oxidising chlorinating and hydrolyzing agent

Answer 2

Preparation of Chloroform from Ethanol.

Explanation:

• Ethanol is first reacted with chlorine to form ethanal which releases out hydrochloric acid.

• Then ethanal is again reacted with an excess of chlorine gas which forms trichloroethanal along with releasing out hydrochloric acid.

$C_{2}H_{5}OH+Cl_{2}$ → $CH_{3}CHO+3Cl_{2}$ → $CCl_{3}CHO$

• The trichloroethanal formed is reacted with calcium hydroxide which releases calcium formate and chloroform.

$CCl_{3}CHO+Ca(OH)_{2}$ → $(HCOO)_{2}Ca+2CHCl_{3}$
