Bonus question Provide an efficient stepwise synthesis for the following.              The answer should be entered as in the following example: (this is an example!) 1. NaNH2   2. CH3CH2Br   3. H2, Lindlar’s Cat.    4. BH3, THF   5. H2O2, NaOH                          (Keep three spaces between each step) All chemicals and reagents  structures should be correct and with the proper sequence. No partial credit.

In which type of polymer are the chains packed less tightly together, resulting in lower melting points and a softer texture?
