An organic compound having molecular mas...

An organic compound having molecular mass `60` is found to contain `C = 20%, H = 6.67%`, and `N = 46.67%`, while rest is oxygen. On heating, it gives `NH_(3)` along with a solid residue. The solid residue gives violet color with alkaline copper sulphate solution. The compounds is

A

`CH_(3)NCO`

B

`CH_(3)CONH_(2)`

C

`(CN_(2))_(2)CO`

D

`CH_(3)CH_(2)CONH_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`C:H:N:O=(20)/(12):(6.67)/(1):(46.67)/(14):(26.66)/(16)`
`M.F=(E.F)_(n)`
`n=("Mol.wt")/("E.F.weight")`
