Question

The general formula of monosaccharides is
A) CnH2n + 20 B) C H200
C) C H2n+1.0 D) C (H20),​

Answer 1

Answer :

✴ Monosaccharides :

→ General formula : (CH2O)n

[ where, n = 3 - 7 ]

→ Monosaccharides can not be hydrolysed further.

→ Eg. Glucose, Fructose, Ribose, etc.

✴ Oligosaccharides :

→ General formula : (C6H10O5)n

[ where, n = 2 - 10 ]

→ Oligosaccharides yield 2 - 10 monosaccharides on hydrolysis.

→ Eg. Sucrose, Maltose, etc.

✴ Polysaccharides :

→ General formula : (C6H10O5)n

[ where n = 100 - 3000 ]

→ Polysaccharides yield large number of monosaccharides on hydrolysis.

→ Eg. Starch, Cellulose, etc.

____________________________

▶ CARBOHYDRATES :

• They are optically active polyhydroxy aldehydes or ketones or the compounds which produce such units on hydrolysis.
• Most of them have a general formula, Cx(H2O)y, and are called as hydrates of carbon.

$\huge\tt{SOLUTION:}$

The general Formula of monosaccharides is :

(CH2O)n

MORE YOU NEED TO KNOW :

• A monosaccharide is the most basic form of carbohydrates.
• Monosaccharides can by combined through glycosidic bonds to form larger carbohydrates, known as oligosaccharides or polysaccharides
• Monosaccharides have the same general formula of (CH2O)n , which designates a central carbon molecule bonded to two hydrogens and one oxygen. The oxygen will also bond to a hydrogen, creating a hydroxyl group.
• Some examples includes , glucose, fructose, ribose , etc.
