Some Basic Principles Of Organic Chemistry Question 74
Question: An organic compound has C = 60%, H = 13.3% and O = 26.7%. Its empirical formula will be
Options:
A) $ C_3H_6O $
B) $ C_2H_6O_2 $
C) $ C_4H_8O_2 $
D) $ C_3H_8O $
Show Answer
Answer:
Correct Answer: D
Solution:
| Elements | No.of moles | Simple ratio |
|---|---|---|
| C 60% | 60/12 = 5 | 3.01 |
| H 13.3% | 13.3/1 = 13.3 | 8.01 |
| O 26.7% | 26.7/16 = 1.66 | 1 |
Empirical formula = $ C_3H_8O $ .
