Question: An organic compound containing C, H and N gave following analysis : C = 40%, H = 13.33% and N = 46.67%. Its empirical formula would be [CBSE PMT 1998, 99; AFMC 2000; KCET 2002; Pb. PMT 2004]
Options:
A) $ C_2H_7N_2 $
B) $ CH_5N $
C) $ CH_4N $
D) $ C_2H_7N $
Show Answer
Answer:
Correct Answer: C
Solution:
| Element | No.of moles | Simple ratio |
|---|---|---|
| C = 40% | 40/12 3.33 | 1 |
| H = 13.33% | 13.33/1 13.33 | 4 |
| N = 46.67% | 46.67/14 3.33 | 1 |
Thus formula $ CH_4N $ .
