Question

A hydro carbon contains 92.3% carbon by mass . Vapour density with respect to hydrogen is 13 . The molecular formula of hydrocarbon is A) C₂H₂ B) C₃H₆ C) C₂H₄ D) C₄H₆ CORRECT ANS ONLY NO SPAMMING PLZZZZZZ

Answer 1

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 )
