QUESTION
Q39) The emperical formula of an organic compound containing carbon and hydrogen is CH2. The mass of one litre of this organic gas is exactly equal to that of one litre of N2. Therefore, the molecular formula of the organic gas is ... [ EAMCET 1985]




SOLUTION

given weight of organic gas for 1 litre=wt of 1 litre of N2
Thus weight of organic gas of 22.4 litre (molecular weight)=wt of 22.4 litre of N2 ( molecular weight)
wt of organic gas=28
x(CH2)=28
x(14)=28
∴ x=2
Answer: (a)
