A scientist discovers a new type of polymer. What must be true about this polymer?
mixas84 [53]

Answer: Option (D) is the correct answer.

Explanation:

A polymer is a large molecule which contains repeating units.

A polymer forms long chain of atoms which are not necessarily arranged in a ring structure. There are not only double bonds between all the carbon atoms, as there can be single bonds or triple bonds between the atoms of a polymer.

A polymer does not contain many different type of molecules as there are many repeating units and not many molecules in a polymer.

A polymer is made of large molecules with repeating units.

Thus, we can conclude that option (D) is the correct answer.
