The weight percentage of C and H in a hydrocarbon is in the ratio of 4: 1 . What is its empirical formula?

Options

  1. ACH
  2. BCH ₂
  3. CCH ₃
  4. DCH ₄

Correct answer

C. CH ₃

Step-by-step solution

M ( c )=12.01, M ( H )=1.0 m ( c )=4 m ( H ) (Given) If n ( c )=1 and n ( H )=3 m ( c )=12.01 and m ( H )=3 and C : H mass ratio =4: 1 Empirical formula = CH ₃ .
