The hydrocarbon (X) with molar mass 80 ~g ~mol ⁻¹ and 90 % carbon has degree of unsaturation.
Correct answer
0
Step-by-step solution
Empirical formula is C ₃ H ₄ Molecular mass =80 ~g ~mol ⁻¹ . Molecular formula = ( C ₃ H ₄ )_ n n = Molecular mass EF mass = 80 40 =2 Molecular formula is C ₆ H ₈ Degree of unsaturation = 2 6+2-8 2 =3
