Match the following Column I Column II (i) CH 3 CO 2 O (a) Ethyl ethanoate (ii) CH 3 COCl (b) Acetic anhydride (iii) CH 3 COOC 2 H 5 (c) Acetyl chloride

Acetic acid on heating with phosphorous pentaoxide loses water and produces acetic anhydride. The acetyl chloride formed by the reaction between acetic acid and phosphorus pentachloride. Ethyl ethanoate is a product formed by the combination of ethanol and acetic acid. Column I Column II i CH 3 CO 2 O Acetic anhydride ii CH 3 COCl Acetyl chloride iii CH 3 COOC 2 H 5 Ethyl ethanoate

A compound X (having vinegar like smell) when treated with ethanol in the presence of the acid, Z, gives a compound Y which has a fruity smell. The reaction is C 2 H 5 O H + X → Z Y + H 2 O Write the structural formula of X.

C 2 H 5 OH + CH 3 COOH → Conc . H 2 SO 4 CH 3 COOC 2 H 5 + H 2 O The X is an acetic acid in this reaction. The structural formula of X is .
