Answer:

(a) Esterification: CH₃COOH + C₂H₅OH ⇌ (conc. H₂SO₄, Δ) CH₃COOC₂H₅ + H₂O (acetic acid + ethanol → ethyl acetate).

(b) With hydroxylamine: CH₃CHO + H₂N–OH —(weakly acidic medium)→ CH₃CH=N–OH + H₂O (acetaldoxime).

(c) Clemmensen reduction: CH₃COCH₃ + 4[H] —(Zn-Hg, conc. HCl)→ CH₃CH₂CH₃ + H₂O (propane). (Wolff–Kishner reduction with NH₂NH₂/KOH in ethylene glycol also gives propane.)
