Q.
A compound A has a molecular formula C2Cl3OH. 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
Molecular formula of A=C2Cl3OH
As (A) reduces Fehling's solution and on oxidation gives a monocarboxylic acid (B). It means (A) must be an aldehyde, i.e. CCl3CHO
This is further confirmed by the reaction, C2H5OH+Cl2OCH3CHO3Cl2NaOHCCl3CHO
Hence, A = Chloral (CCl3CHO)
