A) Methanal
B) Phenol
C) Ethanol
D) Methanol
Correct Answer: C
Solution :
Ethanol, on reaction with bleaching powder, gives chloroform (trichloromethane). \[CaOC{{l}_{2}}+{{H}_{2}}O\xrightarrow{{}}Ca{{(OH)}_{2}}+C{{l}_{2}}\] \[{{C}_{2}}{{H}_{5}}OH+C{{l}_{2}}\xrightarrow{{}}C{{H}_{3}}CHO+2HCl\] \[C{{H}_{3}}CHO+3C{{l}_{2}}\xrightarrow{{}}\underset{Chloral}{\mathop{CC{{l}_{3}}}}\,.\,CHO+3HCl\] \[2CC{{l}_{3}}.CHO+Ca{{(OH)}_{2}}\xrightarrow{{}}\underset{Chloroform}{\mathop{2CHC{{l}_{3}}}}\,\] \[+{{(HCOO)}_{2}}Ca\]
