Which of the following compounds exhibits maximum oxidation state of carbon?

Step-by-step solution

Maximum oxidation state of carbon Oxidation states are calculated using standard values: hydrogen +1, oxygen –2, chlorine –1. For HCHO: x + 2(1) + (-2) = 0 x = 0 For CH₃ OH: x + 3(1) + (-2) + 1 = 0 x = -2 For CHCl₃ : x + 1 + 3(-1) = 0 x = +2 For C₁₂ H₂₂ O₁₁ : 12x + 22(1) + 11(-2) = 0 x = 0 Comparing the oxidation states, carbon reaches its maximum value of +2 in chloroform (CHCl₃ ).
