Question

$CH_3COOH$ when reacts with $C_2H_5OH$ gives a product. The same product is obtained by which reaction ?

• A. Acetic acid $+$ methanol
• B. Acetic anhydride $+$ water
• C. Acetic anhydride $+$ ethanol
• D. Acetamide $+$ methanol

Answer 1

Answer: (C)

Acetic anhydride $+$ ethanol

Answer 2

Acids when react with alcohol form ester. Thus,

$CH_3COOH + C_2H_5OH\rightarrow \underset{\text{ethyl ethanoate}}{CH_3COOC_2H_5} + H_2O$

Acetic anhydride when reacts with ethanol gives the same product, i.e., ethyl ethanoate.
