Question

1. which of the following is not a characteristic of monosaccharides? a. generally a multiple of ch₂o b. can be linked together to make polymers c. contain hydroxyl and carbonyl groups d. all of the above are characteristics of monosaccharides. 2. sweetened beverages from coffee to tea to soda are a regular part of almost everyones daily routine. briefly explain why sugars, like fructose, readily dissolve in water. 3. two monosaccharides joined by a dehydration synthesis would form a(n) __________. list two

Explanation:

1.

Monosaccharides are the simplest carbohydrates. Their general formula is often a multiple of $\mathrm{CH_2O}$. They can be linked by glycosidic bonds through dehydration - synthesis to form polymers (oligosaccharides or polysaccharides). They contain hydroxyl ($-\mathrm{OH}$) and carbonyl ($\mathrm{C=O}$) functional groups. So all the given options are characteristics of monosaccharides.

Sugars like fructose are polar molecules due to the presence of multiple hydroxyl groups. Water is also a polar molecule. According to the principle of "like - dissolves - like", polar fructose molecules interact with polar water molecules through hydrogen bonds, which allows fructose to readily dissolve in water.

Answer:

d. All of the above are characteristics of monosaccharides.
