(i) An organic compound A with molecular formula `C_(7)H_(8)` on oxidation by chromyl chloride in the presence of `C Cl_(4)` gives a compound B which gives positive Tollen's test. The compound B on treatment with NaOH followed by acid hydrolysis gives two product C and D. C on oxidation gives B which on further oxidation gives D. the compound D on distillation with sodalime gives a hydrocarbon E. Below `60^(@)C`, concentrated nitric acid reacts with E in the presence of concentrated sulphuric acid forming a compound F. identify the compounds A,B,C,D,E and F.
(ii) Give chemical test to distinguish : Formaldehyde and acetaldehyde.
