Describe a typical polymer molecule in terms of its chain structure and repeat units. Use a specific example polymer other than polyethylene to illustrate the ideas

Expert Solution

Polymer are long chain C-C chain structure. This C-C bond can take different 3- Dimensional shape by maintaining the same bond angle, this phenomenon is called conformation or bond rotation due to which polymer are extremely soft.

Taking example of Polystyrene - :

It is a synthetic aromatic hydrocarbon polymer.

Its monomer is - Styrene

It is one of the widely used plastic.

The long molecules are composed to structural entities called "mer" which are repeated along the chain. Polymers are mostly amorphous and sometimes partly crystalline. Polystyrene is a thermoplastic, thermoplastic softens when heated and becomes hard when cooled.

Consider the molecule CF3H. Draw the structure for this molecule, then use it to assess each statement. Select all true statements. This molecule is polar because all molecules containing the highly electronegative F atom are polar. The bond angles for this molecule will be less than 109.5 degrees. An electrostatic potential map of this molecule would show a rainbow of colors with the red end of the rainbow at the H atom. This molecule is polar and its dipole runs...
