In the case of esters or amides in # 7, identify which portion of the bond comes from the acid, and which from the other
participating molecule.

10.
Make a distinction between addition polymers and condensation polymers. Show examples of each. For addition polymers,
show ethylene reacting, and ethylene with a chlorine attached reacting. For condensation polymers, show both polyesters
and polyamides forming. Use a separate sheet .
