What chemical property is given to a biomolecule with a hydroxyl (--oh) functional group?
marin [14]

A biomolecule with a hydroxyl (--oh) functional group is given the polar chemical property since organic molecules with an OH group are polar.

 

A part of a larger molecule is made up by a functional group. The hydroxyl group (-OH) that characterizes alcohols, an oxygen with a hydrogen attached, is an example of it. This group can be found on any number of different molecules.

 

Functional groups have characteristic chemistries, just as elements have unique properties., although perhaps not identically, to an -OH on another molecule. Although perhaps not identically to an -OH on another molecule, an -OH group on one molecule will tend to react similarly.

What ultimately determines what type of solution you have? Why can’t we just use this property? Explain in terms of the tyndall
nirvana33 [79]

Answer:

The solutions are classified according to their ability to scatter light rays.

We can't just use this property because some true solutions also contain undissolved solute.

Explanation:

Tyndall effect refers to the ability of a solution to scatter light rays. True solutions do not scatter light rays while false solutions scatter light rays.

Colloid particles are not large enough to be seen with naked eyes unlike suspensions. We should not confuse a colloid with a suspension because in a suspension, the dispersed solutes are seen with naked eye.
