MCQ
Fats, on alkaline hydrolysis, gives
  • A
    Oils
  • Soaps
  • C
    Detergents
  • D
    Glycol + acid

Answer

Correct option: B.
Soaps
b
(b) Fats are esters of higher fatty acids with glycerol, hence on alkaline hydrolysis they give back glycerol and sodium or potassium salt of acid (this is called soap).
