`1 g" urea "(NH_(2)CO NH_(2))`, 1g acetic acid `(CH_(3) COOH)` and 1g of formaldehyde `(HCHO)` will have H-atoms in the ratio.

Options

A. `2 : 2: 1`
B. `1 : 1 : 2`
C. `1 : 1 : 1`
D. `1 : 2 : 1`

Answer

C

Explanation

`1 g" Urea "=(1)/(60) mol =(4N_o)/(60)` H -atom , 1 g acetic acid `=(1)/(60) mol =(4N_o)/(60)` H-atom
1 g formaldehyde `=(1)/(30) mol =(2N_o)/(30)` H -atom `" ".:` the ratio of hydrogen atoms is `1:1:1`.
