A compound A has a molecular formula C2C...

A compound A has a molecular formula C2Cl3OH. It reduces Fehling solution and on oxidation gives a monocarboxylic acid (B). A is obtained by action of chlorine on ethyl alcohol. A is :

A

Chloral

B

`CHCl_3`

C

`CH_3Cl`

D

Chloroacetic acid

Text Solution

Verified by Experts

The correct Answer is:
A
`C_2Cl_3OH+"Fehling sol" rarr underset("Red ppt.")(Cu_2O)`
It means -CHO group is present
`C_2Cl_3OH overset(oxidation)(rarr)underset("Monocarboxylic acid")("CCl"_3)-COOH`
It means only one –CHO group is present.
`C_2H_5OH+Cl_2 rarr CH_3CHO+2HCl`
`CH_3CHO +3 Cl_2 rarr underset("Chloral")"CCl"_3CHO +3HCl`
