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 ammoniacal silver nitrate 'B' when treated with an aqueous solution of `H_(2)NCONHNH_(2)` and sodium acetate gives a product 'C'. Identify the structure of 'C'

Options

A. `CH_(3)CH_(2)CH = N NHCONH_(2)`
B. `CH_(3)-CH = underset(CH_(3))underset(|)(N N)CONH_(2)`
C. `CH_(3)CH= underset(CH_(3))underset(|)(N)CONHNH_(2)`
D. `CH_(3)CH_(2)CH-NCONHNH_(2)`

Answer

A

Explanation

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