Question

a hydro carbon contains 92.3 % carbon by mas . vapour density with respect to H2 is13 the molecular formula of hydrocarbon is 1. C2H2 2. C3H6 3. C2H4 4.C4H8

Answer 1

Answer:

Answer:C2H2

Explanation:

G.T,

Relative vapour density to 'H' =13

ie, M mass=2•V. D

M mass=13×2=26

M mass(C2H2)=(12×2+1×2)=26

So the required Mf is C2H2 (hydrocarbon )
