Alcohols Phenols And Ethers Properties Of Alcohol Phenol And Ethers Question 224
Question: Fats, on alkaline hydrolysis, gives [MH CET 2003]
Options:
A) Oils
B) Soaps
C) Detergents
D) Glycol + acid
Answer:
Correct Answer: B
Solution:
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). $ \underset{Fat}{\mathop{\underset{CH_2OCOR}{\overset{CH_2OCOR}{\mathop{\underset{|}{\overset{|}{\mathop{C}}},HOCOR\ }}},}},+3NaOH\to \underset{CH_2OH}{\overset{CH_2OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}},HOH\ }}},+\underset{\text{(Soap)}}{\mathop{3RCOONa}}, $
