Sodium fusion extract of an organic compound gives blood red colour with `FeSO_(4)//Conc. H_(2)SO_(4)` on heating. Fresh extract of the same compound gives black precipitate when mixed with `(CH_(3)COO)_(2)Pb` and with yellow precipitate when treated with `AgNO_(3)` solution. Then the organic compound may be

Options

A. `C_(6)H_(12)NCl`
B. `C_(6)H_(12)NI`
C. `C_(6)H_(12)NSI`
D. `C_(6)H_(12)SI`

Answer

C

Explanation

Blood red colour with `FeSO_(4)//com. H_(2)SO_(4)` by S.F.E `rArr` the compound has both N and S
Black precipitate with lead acetate by S.F.E. `rArr` the compound has S.
Yellow precipitate with `AgNO_(3)` by S.F.E. `rArr` the compound has I.
