Compound 'A' (molecular formula ) is treated with acidified potassium dichromate to form a product ' B ' (molecular formula ). ' B ' forms a shining silver mirror on warming with ammoniacal silver nitrate. ' B ' when treated with an aqueous solution of and sodium acetate gives a product ' C '. Identify the structure of ' C '.

Question diagram: Compound 'A' (molecular formula C 3 ​ H 8 ​ O ) is

Options:

Answer:
A
Solution:

 

A (C₃H₈O) = 1-propanol

Oxidation (K₂Cr₂O₇/H⁺) → B (C₃H₆O) = propanal (Tollens +ve)

Propanal + semicarbazide → semicarbazone
