Dichloroacetic acid (CHCl₂COOH) is oxidized to CO₂, H₂O and Cl₂ by 600 meq of an oxidizing agent. Same amount of acid can be neutralized by how many moles of ammonia to form ammonium dichloroacetate?
Options:
Answer:
B
Solution:
In CHCl₂COOH the average oxidation state of C is +2; oxidation to 2CO₂ releases 4e⁻, and 2Cl⁻ Cl₂ releases 2e⁻, i.e. 6e⁻ per molecule. 600 meq corresponds to 600/6 = 100 mmol = 0.1 mol of acid. The acid is monoprotic, so NH₃ needed = 0.1 mol, option (b).
