Describe the bonding in a carbon-carbon double bond. Include in this description an explanation of the mechanism by which the various bonds are formed. What does the existence of a double bond tell about the other atoms bonded to the carbon atoms?
 
  What will be an ideal response?

Question 2

Why is it harder to make very long polymer chains using the condensation polymerization method than by using the addition polymerization method?
 
  What will be an ideal response?

Answer to Question 1

A carbon-carbon double bond assumes that each carbon is bonded to three atoms

Answer to Question 2

In the condensation reaction every monomer molecule can react with equal probability upon encountering any monomer of the opposite type. This situation favors the formation of many small chains which grow simultaneously. As the chains get larger, their ability to continue reacting is slightly less than small chains because the large chains have less mobility and, therefore, less chance to encounter a monomer with which it can react. Also, in condensation polymerization the byproduct of water is formed as the monomers react. The presence of water molecules in the reaction will hinder chain formation by diluting the reactants. In addition polymerization, encounters between monomers do not form bonds unless one of the monomers has been initiated, that is, reacted with an initiator so that the monomer contains a free radical. Therefore, in addition polymerization, since only a few of the monomers are initiated, the growth of the chains will be largely at the sites that are on the already formed polymers, thus making those polymer chains even longer.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
