Question

Carbohydrate(s) which can be hydrolysed to a simpler compound is:

• A. Monosaccharide
• B. Polysaccharide
• C. Disaccharide
• D. Trisaccharide

Answer 1

Answer: (B), (C), (D)

Trisaccharide

Carbohydrates are classified based on number of monomers obtained after hydrolysis as follows:
(i) Monosaccharides (no further hydrolysis)
(ii) Disaccharides (gives two monomers on hydrolysis)
(iii) Trisaccharides (gives three monomers on hydrolysis)
(iv) Oligosaccharides (gives $3-10$ monomers on hydrolysis)
(v) Polysaccharides (gives more than $10$ monomers on hydrolysis)

Monosaccharides: Simplest form of carbohydrate which cannot be hydrolysed further. They have general formula${\left(C{H}_{2}O\right)}_{n.}$
Hence, (a), (b) and (c) are correct.
