Answer:
C₆₀H₁₀₂O₅₁
Explanation:
Monosaccharides (monomers) like glucose join together to form a long chain compound called as polymer. These monosachharides are joint together by a bond called as Glycosidic bond which formed by the elimination of water molecule. i.e.
R--OH + R--OH → R--O--R + H₂O
In above reaction R----O----R is known as Glucosidic Linkage.
The number of water molecules formed during a polymerization reaction are calculated as,
Number of Monomers - 1 = Number of Water molecules
As, the number of Glucose molecules given are 10, so,
Number of Glucose - 1 = Number of Water molecules
10 - 1 = Number of Water molecules
Number of Water Molecules = 9
Molecular Formula of Polymer is found as,
As one molecule of Glucose (C₆H₁₂O₆) contains 6 Carbon, 12 Hydrogen and 6 Oxygen atoms so, 10 molecules will contain,
= C₆H₁₂O₆ × 10
= C₆₀H₁₂₀O₆₀
Also, we know one water molecule contain 2 Hydrogen and 1 Oxygen atom therefore, 9 water molecules will contain
= H₂O × 9
= H₁₈O₉
Now subtracting H₁₈O₉ from C₆₀H₁₂₀O₆₀,
Molecular Formula = C₆₀H₁₂₀O₆₀ - H₁₈O₉
Molecular Formula = C₆₀H₁₀₂O₅₁
The Macromolecule formed and the water molecules eliminated are well shown in figure attached below,
