Compound A (molecular formula `C_3 H_8 O`) is treated with acidifed potassium dichromate to form a product B (molecular formula `C_3 H_6 O`). B forms a shining sliver 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 =NHHCONH_2`
B. `(CH_3)_2 C= NNHCOCNNH_2`
C. `(CH_3)_2 C= NCONH NH_2`
D. `CH_3 CH_2 CH = NCONH NH_2`

Answer

A

Explanation

`underset((A) )( CH_3 -CH_2 -CH_2 -OH underset(H^+ ) overset(K_2 Cr_2 O_2 ) to CH_3 - CH_2 - overset( O) overset(||) C-H` (B) gives silver mirror test
