(a)
Interpretation: The numbers of monomers are affected by the necking effect has to be identified.
Concept Introduction:
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
Necking is formed when piece of plastic bag is stretched. During stretching the dispersion force arise in the polymer since each atom in the chain contains electrons with it and these electrons are attracted to neighboring atoms.
As the plastic bag is stretched the length increase and the width decreases creating a small shoulder at wider part and narrow neck which is called necking.
(b)
Interpretation: The process necking affect the bonding between the monomer units has to be identified.
Concept Introduction:
Polymers: Polymers are macromolecules which are formed a by number of repeating units called monomers.
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.
As the plastic bag is stretched the length increase and the width decreases creating a small shoulder at wider part and narrow neck which is called necking.
