Interpretation Introduction

Interpretation:

The reason for the brittleness of the objects and balls made up of natural rubber when exposed to air for longer periods should be given.  Also the reason behind slowness in objects made of polyethylene should be determined.

Concept Introduction:

Polymers:

Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.

Two types of polymers:

  • Synthetic and biopolymers.
  • DNA is an example for biopolymer and these type of polymers are synthesized by cells.
  • Polymers synthesized by scientists are called synthetic polymers and some examples are nylon, polyester etc.

Natural rubber:

  • Monomer unit is isoprene unit (2-methyl-1,3-butadiene)
  • The double bonds in natural rubber is having Z configuration.
  • There will be appropriately 5000 isoprene units in a molecule of rubber.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction.
