An organic compound contains ( C =40 %, H =13.33 % ) and ( N =46.67 % . ) Its emperical formula is

Options

  1. A( C₂ H₂ N )
  2. B( C ₃ H ₇ ~N )
  3. C( CH ₄ ~N )
  4. DCHN

Correct answer

C. ( CH ₄ ~N )

Step-by-step solution

For the empirical formula of the given compound array |l|l|l|l| Element & Percentage & Relative number of moles & Simplest ratio of moles C & ( 40 ) & ( 40 12 =3.33 ) & ( 3.33 3.33 =1 ) H & ( 13.33 ) & ( 13.33 1 =13.33 ) & ( 13.33 3.33 =4 ) N & ( 46.67 ) & ( 46.67 14 =3.33 ) & ( 3.33 3.33 =1 ) array Thus, the compound has the empirical formula ( CH ₄ ~N ).
