Complete combustion of of a hydrocarbon gives of and of . The lowest molecular mass can have
16 g
86 g
129 g
172 g
Given,
Mass of = 2.2 g Moles of = 0.05
Mass of = 1.8 g Moles of = 0.1
We know, combustion of any hydrocarbon is given as
We have,
The only hydrocarbon which satisfies the above condition is
