Chapter 5 Sec 1

Summary

• This section talks about the carbon skeletons of molecules, monomers and polymers.
• The carbon atoms is in most cases the backbone of many molecules, since carbon atoms can form up to four bonds and form long strings of molecules.
• Monomers are the smaller molecular units that make up what a bigger molecules. Polymers the strings that are made up of monomers, these chain can be created when two or more monomers bond together in a dehydration reaction and afterwards the produce a H2O molecule. But to break a bond you add a water molecule to the chains and the reaction is the hydrolysis.

Concept Check

1. Draw a molecule and has a three-carbon skeleton and a hydroxyl group on the middle group.

2. Explain the connection between monomers and polymers.

Monomers are the small molecular units that make up the long chains of polymers, they held together by bonds.

3. What molecule is released during construction of a polymer? What is the reaction called?

A water molecule is released when a polymer is constructed and the reaction is known as dehydration reaction.

4. Draw at least three ways in which five carbon atoms could be joined to make different carbon skeletons.
