monomers
10. The following is what type of reaction: C2H5OH + C2H6 → C4H10 + H2O
dehydration synthesis
What are the products of dehydration synthesis?

1. Imagine you are working in a lab to determine the nature of an unknown type of polymer. Through your experimentation, you denature (break down) the polymer into monomers, which happen to be amino acids.
Under which group of organic polymers would you categorize your polymer? Why did you choose this group?
proteins, b/c they are made up of amino acids
(Free Response):
Chemical reactions are important for the synthesis and recycling of organic matter. Explain dehydration synthesis by writing out a simple reaction using the words monomer, polymer and water.
monomer + monomer --> polymer + water
6. What role does dehydration synthesis play in the creation of advanced organic molecules?
D.S. joins smaller molecules to make larger, more complex molecules (polymers) that are needed for life!
11. Suppose you were stranded on a desert island with no food or water. You are allowed to choose a machine that conducts either dehydration synthesis or hydrolysis for your utilization. Which do you choose and why?
Dehydration synthesis, because water would be formed by the reaction
**challenge**
In order to break apart a polymer, what molecule must be added? (it acts as a pair of scissors)
water
(Free Response):
Chemical reactions are important for the synthesis and recycling of organic matter. Explain hydrolysis by writing out a simple reaction using the words monomer, polymer and water.
polymer + water --> monomer + monomer
5. Compare and contrast the processes of dehydration synthesis and hydrolysis. Be sure to include the role of water in these processes.
~Both involve water
~Dehydration synthesis = removing a water molecule to join two smaller molecules into a larger molecule
~Hydrolysis = adding a water molecule to split a large molecule into 2 smaller molecules
7. Would you use hydrolysis or dehydration synthesis to break a larger molecule into two smaller molecules? Support your answer.
Hydrolysis. Hydrolysis breaks large molecules apart.
**challenge**
Which reaction type (dehydration synthesis or hydrolysis) ENDS with a polymer as A PRODUCT?

**challenge**
00000 + water --> 000 + 00
what is this reaction an example of?
hydrolysis
