The compound 'C' in the following reaction is
o-bromotoluene
m-bromotoluene
p-bromotoluene
3-bromo-2, 4, 6-trichlorotoluene
Compound (A) (molecular formula C3H8O) is treated with acidified potassium dichromate to form a product B (molecular formula C3H6O). 'B' forms a shining silver mirror on warming with ammoniacal silver nitrate. 'B' when treated with an aqueous solution of H2NCONHNH2 · HCl and sodium acetate gives a product C'. Identify the structure of 'C
A.
(i) Aldehydes reduce ammoniacal AgNO3 to silver mirror.
(ii)
(iii) Aldehydes give addition product with ammonia derivative.
