A hydrocarbon contains 20% hydrogen and 80% carbon.The empirical formula is
Options
(a) CH₄
(b) CH₃
(c) CH₂
(d) CH
Correct Answer:
CH₃
Explanation:
Atomic ratio of 20% Hydrogen = 20 / 1 = 20
Atomic ratio of 80% Carbon = 80 / 12 = 6.6
Simple ratio of 20% Hydrogen = 20 /6.6 = 3.03
Simple ratio of 80% Carbon = 6.6 / 6.6 = 1
so, the empirical formula is CH₃.
