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

Answer»

chloral
chloroform
chloromethane
chloroacetic acid.

Solution :Since COMPOUND A REDUCES Fehling.s solution and on OXIDATION gives a monocarboxylic acid B, it must be aldehyde. Further since A is OBTAINED by the action of `Cl_(2)` on `C_(2)H_(5)OH`, therefore, A is chloral.
`C_(2)H_(5)OH overset(Cl_(2))to underset("Chloral (A)")(C Cl_(3)CHO) overset([O])to underset("Trichloroacetic acid (B)")(C Cl_(3)COOH)`
