Some Basic Principles Of Organic Chemistry Question 80
Question: An organic compound with C = 40% and H = 6.7% will have the empirical formula [MP PET 1999; JIPMER 2002]
Options:
A) $ CH_2 $
B) $ CH_2O $
C) $ C_3H_6O_3 $
D) $ C_2H_4O_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
| Elements | No.of moles | Simple ratio |
|---|---|---|
| C = | 40% 40/12 3.33 | 1 |
| H = | 6.7% 6.7/1 6.7 | 2 |
| O = | 53.3% 5.33/16 3.33 | 1 |
Thus, Empirical formula = $ CH_2O $ .
