Acetic anhydride is prepared in the laboratory by heating sodium acetate with

Options

  1. Aethyl chloride
  2. Bacetyl chloride
  3. Cconc. H2SO4\mathrm{H}_2 \mathrm{SO}_4
  4. Dzinc dust

Correct answer

B. acetyl chloride

Step-by-step solution

In laboratory, acetic anhydride is prepared by heating sodium acetate with acetyl chloride. CH3COONa+CH3COCl acetyl chloride \mathrm{CH}_3 \mathrm{COONa}+\underset{\text{ acetyl chloride }}{\mathrm{CH}_3 \mathrm{COCl}}\xrightarrow[-NaCl\mathrm{NaCl}]{\Delta}CH3COOCOCH3 acetic anhydride \underset{\text{ acetic anhydride }}{\mathrm{CH}_3 \mathrm{COOCOCH}_3}
