Some Basic Concepts Of Chemistry Question 291
Question: A compound (80 g) on analysis gave C = 24 g, H = 4 g, O = 32 g. Its empirical formula is [CPMT 1981]
Options:
A) $ C _2H _2O _2 $
B) $ C _2H _2O $
C) $ CH _2O _2 $
D) $ CH _2O $
Show Answer
Answer:
Correct Answer: D
Solution:
$ C=24gm $ , $ H=4gm $ , $ O=32gm $
So, Molecular formula $ =C _2H _4O _2 $
So, Empirical formula $ =CH _2O $
(Simplest formula).
