Question

A Hydro carbon has C = 5.72 and remaining ‘H’ than Hydrocarbon is-

• A. C₂ H₄
• B. C_{2 ­}H₆
• C. C₂ H₂
• D. CH₄

Answer 1

Answer: (A)

C₂ H₄

Answer 2

C : H = $\frac{85.72}{12}$ : $\frac{14.28}{1}$ = 1 : 2

So, empirical formula is CH₂ and its molecular formula would be a simple multiple of CH₂ i.e CH₂ × 2 = C₂H_4.
