Compound A (molecular formula `C_(3)H_(8)O` ) is treated with acidified potassium dichromate to form a product B (molecular formula `C_(3)H_(6)O`) . B forms a shining silver mirror on warming with ammonical silver nitrate , B when treated with an aqueous solution of `NH_(2)NHCONH_(2)` and sodium acetate gives a product C . identify the structure of C .

Options

A. `CH_(3)CH_(2)CH=NNHCONH_2`
B. `CH_3-CH=underset(CH_3)underset(|)NNHCONH_2`
C. `CH_3CH=underset(CH_3)underset(|)NCONHNH_2`
D. `CH_(3)CH_(2)CH-NCONHNH_2`

Answer

A

Explanation

`CH_(3)-underset((A))(CH_2)-CH_(2)OH overset([O]) rarr CH_(3)-underset((B))(CH_2)-CHO`
`CH_(3)-CH_(2)-overset(H)overset(|)C=O + H_(2)N NHCONH_2 overset(HC) rarr CH_(3)CH_(2)CH = N-NHCONH_2`
