Question

Identify correct conversion during acidic hydrolysis from the following: 
(A) Starch gives galactose. 
(B) Cane sugar gives equal amount of glucose and fructose. 
(C) Milk sugar gives glucose and galactose. 
(D) Amylopectin gives glucose and fructose. 
(E) Amylose gives only glucose. 
Choose the correct answer from the options given below:

• A. (B), (C) and (E) only
• B. (B), (C) and (D) only
• C. (A), (B) and (C) only
• D. (C), (D) and (E) only

Hint:

Remember that sucrose gives glucose and fructose, lactose gives glucose and galactose, and starch yields glucose.

Answer 1

The Correct Option is A

- (B) Cane sugar (Sucrose) undergoes hydrolysis, yielding an equimolar mixture of glucose and fructose.
- (C) Milk sugar (Lactose) hydrolyzes to produce glucose and galactose.
- (E) Amylose, a linear polysaccharide composed of glucose units, hydrolyzes exclusively into glucose.
- (A) is incorrect: Starch breakdown yields maltose and subsequently glucose, not galactose.
- (D) is incorrect: Amylopectin hydrolyzes into glucose, not fructose.
