When acetone reacts with bleaching powder, the compound formed is

Options

(a) CCl₄
(b) CHCl₃
(c) CH₃CHO
(d) CH₃COOH

Correct Answer:

CHCl₃

Explanation:

It involves two steps: CaOCl₂(Bleaching powder) + H₂O → Ca(OH)₂ + Cl₂ . (i)Chlorination of acetone to form trichloroacetone. CH₃COCH₃ + 3Cl₂ → CCl₃COCH₃ + 3HCl. (ii) Trichloroacetone is hydrolysed by Ca(OH)₂ present in bleaching powder to give chloroform. 2CCl₃COCH₃ + Ca(OH)₂ → 2CHCl₃(Chloroform) + (CH₃COO)₂Ca(Calcium acetate).
