One per cent composition of an organic compound A is, carbon : 85.71 % and hydrogen 14.29 % . Its vapour density is 14 . Consider the following reaction sequence Identify C ,

Step-by-step solution

aligned & C =85.71 % = 85.71 12 =7.14 ; 7.14 7.14 =1 & H =14.29 % = 14.29 1 =14.29 ; 14.29 7.14 =2 aligned Empirical formula = CH ₂ and, empirical formula weight =12+2=14 Again, molecular formula weight aligned & =2 vapour density & =2 14=28 n & = 28 14 =2 aligned Molecular formula = ( CH ₂ )₂= C ₂ H ₄
