Some Basic Principles Of Organic Chemistry Question 66
Question: An organic compound contains $ C=38.8%, $ $ H=16% $ and $ N=45.2% $ . Empirical formula of the compound is [CPMT 1973, 83]
Options:
A) $ CH_3NH_2 $
B) $ CH_3CN $
C) $ C_2H_5CN $
D) $ CH_2{{(NH)}_2} $
Show Answer
Answer:
Correct Answer: A
Solution:
| Element | No.of Moles | Simple Ratio |
|---|---|---|
| C = 38.8 | 38.8/12 = 3.2 | 1 |
| H = 16 | 16/1 = 16 | 5 |
| N = 45.2 | 45.2/14 = 3.2 | 1 |
Therefore, Empirical formula = $ CH_5N $ or $ CH_3NH_2 $ .
