Step 1
Step 2
Step 3
Step 4
Explain why the functional groups that link the monomers in protein are oriented differently from the functional groups that link the monomers in nylon.
Answer
In nylon, the amide groups formed from the condensation reaction between the monomers are oriented in opposite directions due to the structures of the individual monomers. This creates a linear chain structure. Conversely, in proteins, the functional groups are oriented in the same direction due to the inherent structure of the amino acids involved, allowing for specific folding and function. The orientation affects the properties and behavior of the resulting polymers.
Step 5
Draw a section of the polymer showing at least two units of the monomer.
Answer
The structure of Perspex, showcasing two repeating units of methyl methacrylate, can be represented as:
[ -C(=O)-O-CH3 ]

[ -C(=O)-O-CH3 ]
This visually represents the polymer chain made from the monomers.
