Some Basic Principles Of Organic Chemistry Question 79
Question: Empirical formula of a hydrocarbon containing 80% carbon and 20% hydrogen is [MP PET 1997; EAMCET 1998; JIPMER 2002]
Options:
A) CH
B) $ CH_2 $
C) $ CH_3 $
D) $ CH_4 $
Show Answer
Answer:
Correct Answer: C
Solution:
| Elements | No.of moles | Simple ratio |
|---|---|---|
| C = 80% | 80/12 = 6.66 | 1 |
| H = 20% | 20/1 = 20 | 3 |
Hence, Empirical Formula = $ CH_3 $ .
