Sucrose is a:

a. Monosaccharide b. Disaccharide
c. Reducing sugar d. Non-reducing sugar

Choose the correct option:

1. a and b 2. b and c
3. c and d 4. b and d
HINT: Sucrose is non-reducing sugar.
Explanation:
Sucrose on hydrolysis produces an equimolar mixture of α-D(+) glucose and B-D(-)- fructose. Since in sucrose C-1 of glucose and C-2 of fructose are linked with each other. It is a disaccharide.

So, they are non-reducing in nature.
