Some Basic Principles Of Organic Chemistry Question 57
Question: On complete combustion 1.4 g hydrocarbon gave 1.8 g water. Empirical formula of the hydrocarbon is
Options:
A) $ CH $
B) $ CH_2 $
C) $ CH_3 $
D) $ CH_4 $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \because $ 1.8gm water obtained from 1.4gm hydrocarbon
$ \therefore $ 18gm water obtained from - $ \frac{1.4}{1.8}\times 18=14 $ gm.
Empirical formula Mass = 14
$ \therefore $ Empirical formula = $ CH_2 $ .
