A compound A has a molecular formula `C_(2) CI_(3),OH`It reduces Fehling's solution and on oxidation, gives a monocarboxylic acid B. A can be obtained by the action of chlorine on ethyl alcohol. A is

Options

A. chloroform
B. chloral
C. methyl chloride
D. monochloroacetic acid

Answer

a

Explanation

Molecular formula of `A = C_(2)CI_(3)OH`
As (A) reduces Fehling.s solution and on oxidation gives a monocarboxylic acid (B). It means (A) must be an aldehyde.
`underset((A))(CCI_(3)CHO)`
This is further confirmed by the reaction
`C_(2)H_(5)OH+CI_(2)overset([O])toCH_(3)underset(CI_(2))(CHO)tounderset("CC"I_(3)CHO)`
`A = chloral ("CC"I_(3)CHO)`
