Using the Polymers: A Property Database provide the following
Novosadov [1.4K]

Polyethene is a polymer composed of repeating units of the monomer ethene.

The properties of polyethene are as follows:

  • density- ranges 0.857 g/cm3 to 0.975 g/cm3.
  • specific heat capacity is 1.9 kJ/kg.
  • melting temperature is approximately 110 °C.

<h3>What are polymers?</h3>

Polymers are large macromolecules consisting of long repeating chains of smaller molecules known as monomers.

An example of a polymer is polyethene composed of repeating units of the monomer ethene.

The density of polyethylene ranges 0.857 g/cm3 to 0.975 g/cm3.

The specific heat capacity of polyethene is 1.9 kJ/kg.

The melting temperature of polyethene is approximately 110 °C.

Using only the 1h nmr spectrum of the crude nitration product, determine if the product is mostly ortho-, meta-, or para- substi
tatiyna
<span>The nitartion of methyl benzoate is expected to proceed as given in the equation below:

</span>

In methyl benzoate there are 3 types of 1 H proton. The two ortho to the C=O group is a doublet at 8 ppm the 2 metal to the C=O is a multiple at 7.5 ppm and one para to the C=O is a multiplet at 7.5 ppm.

On nitration the ortho will probably show two signal one being a single with 3 proton integration and one a doublet with 1 H integration

The meta will show a highly down field singlet (coresponding to 1 proton), two unequal doublets (corresponding to 1 H each) and one multiplets (corresponding to 1H). This is the major product as seen from the 1H NMR.

The para isomer will come as two doublets which will be very close to each other there is a small signal for this set between 8.2 and 8.3 ppm.
