Question
In a hydrocarbon, mass ratio of hydrogen and carbon is 1 : 3, The empirical formula of hydrocarbon is
Options
A.CH4
B.CH2
C.C2H
D.CH3
Solution
Mass ratio of H : C = 1 : 12
However given mass ratio of H : C =1 : 3
Therefore, for every C atom, There are 4 H atoms, hence empirical formula = CH3
