III.A second product,like water,is also formed during the polymerization process.
A)I only
B)I and II
C)II only
D)I and III

Accepted Answer

Remember that some atoms are removed when the monomers link.

Question 16

Consider the process of condensation polymerization.Which statement is false?
A)A small molecule like water is often formed as the monomers combine to form the polymer.
B)The product contains all of the atoms of the starting materials.
C)PET is formed using this process.
D)Nylon is formed using this process.

Accepted Answer

Either a small molecule is lost or all starting atoms remain,not both.
