Complete the polymer tutorial, available on ChemistryLand: http://www.chemistryland.com/PolymerPlanet/Polymers/PolymerTutorial.htm

The structure above represents a portion of a polymer chain.

Write a response that addresses the following questions:

Explain how based on its structure and functional groups, what properties would this polymer have? Would it be elastic or rigid?

Would it be dissolved easily by hydrocarbon solvents (like gasoline)?

Would it have a low or high melting point?

Consider the same polymer without the pendant isopropyl groups (replace them with hydrogens). What changes would occur to the polymer properties?

Note. Initial answers to the discussion question must be substantive and Professional in the range of 350-450 words.

Question 2 Polycyclic Aromatic Hydrocarbons

Review the effects of Polycyclic Aromatic Hydrocarbons (PAHs) by reading the summaries in the Agency for Toxic Substances & Disease Registry website: http://www.atsdr.cdc.gov/ToxProfiles/TP.asp?id=122&tid=25

Write a response that addresses the following questions:

What are the health risks for Polycyclic Aromatic Hydrocarbons?

Where have these compounds been found?

Have you been exposed to these compounds?

What are the health risks associated with e-cigarettes? What compounds in e-cigarettes have been linked with health risks?

e-Cigarettes have been touted as being responsible for assisting the cessation of smoking of regular cigarettes. Do the benefits of e-cigarettes outweigh the health risks?

Note. Initial answers to the discussion question must be substantive and professional and in the range of 350-450 words.
