The three functional groups shown in the image are: ester, alkoxy and carboxyl.
<h3>What are functional groups?</h3>
Chemical properties depend on its structure. Certain properties, too, are attributable to an atomic group ordered in a particular way, apart from the whole of the molecule. Such groups of atoms that determine the chemical properties of compounds are called<em> functional groups</em>.
The functional group can be on the primary, secondary, or tertiary carbon.
Functional groups are often found on molecules of biological importance.
Functional groups are usually formed by a set of elements such as carbon, hydrogen and oxygen, attached to the hydrocarbon chain, giving the molecule characteristics. Can also include other elements such as sulfur or nitrogen.
Molecules can have more than one functional group on it, having different combinations on it that can affect properties of the molecule such as solubility, structure, or reactivity.
Carboxyl groups are usually seen in amino acids, fatty acids and other molecules since it is a fairly common functional group.
Therefore, we can confirm that the three functional groups shown in the image are: ester, alkoxy and carboxyl.
