Some Basic Principles Of Organic Chemistry Question 51
Question: A compound contains $ C=90% $ and $ H=10% $ . Empirical formula of the compound is [NCERT 1976; EAMCET 1978]
Options:
A) $ C_3H_{10} $
B) $ CH_2 $
C) $ C_3H_2 $
D) $ C_3H_4 $
Show Answer
Answer:
Correct Answer: D
Solution:
| Elements | No.of Moles | Simple ratio |
|---|---|---|
| C = 90% | 90/12 = 7.5 7.5/7.5 = 1 $ \times $ 3 | = 3 |
| H = 10% | 10/1 = 10 10/7.5 = 1.33 × 3 | = 4 |
Empirical formula = $ C_3H_4 $
