In a compound C, H and N atoms are present in 9 : 1 : 3.5 by weight. Mol wt. of compound is 108, its mol. formula is

A

`C_2H_6N_2`

B

`C_3H_4N`

C

`C_6H_8N_2`

D

`C_9H_(12)N_3`

Text Solution

Verified by Experts

The correct Answer is:
C
`13.5 g = 9gC = 1 gH -=3. gN`
`:. 108 g -= (9xx108)/(13.5) gC -=(1xx108)/(13.5)g H -= (3.5xx108)/(13.5) gN`
`-= (9xx108)/(13.5xx12)mol C =(1xx108)/(13.5xx1) "mol H "= (3.5xx108)/(13.5xx14) mol N " " :. ` Molecular formula `=C_6H_8N_2`
