Polymers And Synthesis

Question 1

Zwitterion

Answer 1

A dipolar ionic form of an amino acid that is formed by the donation of a hydrogen ion from the carboxyl group to the amino group. Because both charges are present there is no overall charge

Question 2

Isoelectric point

Answer 2

Is the ph value at which the amino acid exists as a zwitterion

Question 3

Condensation reaction

Answer 3

A reaction in which two small molecules react together to form a larger molecule with the elimination of a small molecule such as water

Question 4

Stereoisomers

Answer 4

Species with the same structural formula but with a different arrangement of the atoms in space

Question 5

Chiral carbon

Answer 5

A carbon atom attached to four different atoms or group of atoms

Question 6

Optical isomers

Answer 6

Stereoisomers that are non superimposable mirror images of each other

Question 7

Repeat unit

Answer 7

The specific arrangement of atom that occurs in the structure over and over again, repeat units are included in brackets, outside which is the letter n

Question 8

Biodegradable polymer

Answer 8

A polymer that breaks down completely into carbon dioxide and water

Question 9

Degradable polymer

Answer 9

A polymer that breaks down into smaller fragments when exposed to light, heat or moisture

Question 10
