Chemistry 4.1.3.

Question 1

Biodegradable polymer

Answer 1

polymers which can be broken down by microorganisms, where light and water are required for digestion.

Question 2

Cis-trans isomerism

Answer 2

(E.g. of E/Z isomerism) where two of the groups attached to each carbon atom of the carbon double bond are the same, with one of the groups being hydrogen.

Question 3

Electrophile

Answer 3

an electron pair acceptor.

Question 4

E/Z isomerism

Answer 4

(E.g. of stereoisomerism) in terms of restricted rotation about the carbon double bond and the requirement for two different groups to be attached to each carbon atom of the carbon-carbon double bond.

Question 5

Photodegradable polymer

Answer 5

Polymers which can be broken down by UV light.

Question 6

Stereoisomer

Answer 6

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