How does Sp2 hybridized carbon play a role in polymers In r

How does Sp2 hybridized carbon play a role in polymers :

In relation to polymer formation by addition and condensation

In relation to polymer backbones

In relation to functional reactive groups

In relation to 2 different elements from group 6 of the periodic table.

In relation to isomers

In relation to conductivity of the polymer

Solution

Polymers have a continous backbones Sp² hybidrized carbons. Sp² orbital have 1 unpaired electron per carbon.

Three Sp² carbon atoms form a 3-dimensional to attain stable configuration whereas unmixed p_z orbital is located perpendicular to the 3-d formed ba 3 Sp² carbons space.

The Sp² carbons form sigma bonds and p_zorbital form pi bond. The p_z orbital of a polymer form pi overlap that results in the delocalisation of electrons in polymer chain.
