Dichloroacetic acid (CHCl₂CO₂H) is oxidized to CO₂, H₂O and Cl₂ by 1.2 equivalents of an oxidizing agent. Same amount of the acid can neutralize 'X' moles of NH₃ to give ammonium dichloroacetate. 'X' is

TestHub · Accepted Answer

In CHCl₂CO₂H the two C atoms total +4 (avg +2); oxidation to 2CO₂ (C total +8) releases 4 e⁻, and 2Cl⁻ → Cl₂ releases 2 e⁻: 6 e⁻ per mole of acid, so n = 6. Moles of acid = 1.2/6 = 0.2. Neutralization is 1:1 with NH₃, so X = 0.2. Hence (c).
