Ageneticist has discovered a new compound that is made up of a small number of identical subunits. the subunits are joined end to end in long chains. based on this information, what best can be concluded about these subunits? they are ketones. they are hydrocarbons. they are monomers. they are polymers. the answer will not be polymers

The correct answer is they are monomers.

Explanation:

For the given options:

Option 1: Ketones are a type of functional groups which change the function of an organic molecule. The compound formed with ketones in them are termed as carbonyl compounds.

Option 2: Hydrocarbons are the compounds which contain a covalent bond between hydrogen and carbon atoms. These compounds are also known as organic molecules.

Option 3: Monomers are the small units which combine together to form a chain. These are the repeating units in a polymer.

Option 4: Polymers are defined as a molecule which is formed by joining several units of small molecules known as monomers.

From the above information, it is visible that the correct answer is Monomers.
