What is the main characteristic of addition polymerization?

• It involves the formation of triple bonds.

• It requires the presence of double bonds.

• It involves the removal of water molecules.

• It occurs only in natural polymers.

In addition reactions, what happens to the double bond?

• It remains unchanged.

• It is replaced by a triple bond.

• It is strengthened.

• It is broken and new atoms are added.

What type of bond is formed when two atoms share one pair of electrons?

• Metallic bond

• Double covalent bond

• Single covalent bond

• Ionic bond

What is a substitution reaction?

• Adding atoms to a double bond

• Replacing atoms in a single bond

• Forming a new double bond

• Breaking a triple bond

What distinguishes condensation polymerization from physical condensation?

• It only occurs in gaseous substances.

• It does not involve any chemical changes.

• It involves a change in physical state.

• It is a chemical reaction forming new compounds.

In condensation reactions, what is typically formed as a byproduct?

• Oxygen gas

• Water

• Carbon dioxide

• Hydrogen gas

Which group is involved in condensation reactions to form water?

• Carboxyl group (COOH)

• Phosphate group (PO4)

• Amino group (NH2)

• Hydroxyl group (OH)

What happens to molecules during condensation polymerization?

• They break apart into smaller units.

• They form ionic bonds.

• They remain unchanged.

• They join together, releasing water.
