Introduction to Organic Chemistry AS

Question 1

Define Structural Isomers

Answer 1

Isomers with the same molecular formula, but different structural formulas.

Question 2

Explain Chain Isomers

Answer 2

Have the same functional groups but different carbon arrangements

Question 3

Explain Positional Isomers

Answer 3

Functional groups are attached to different carbon atoms.

Question 4

Explain functional group isomers

Answer 4

Same atom arrangements but are a part of a different homologous series

Question 5

What is sterioisomerism?

Answer 5

Molecules with the same molecular and structural formula but a different arrangement of the atoms in space.

Question 6

How do you know if molecules have E/Z isomerism?

Answer 6

If both C of the C=C have two of the same groups attached

Question 7

Explain E-isomers

Answer 7

Have the same group positioned across the double bond.

Question 8

Explain Z-isomers

Answer 8

Have the same group either (both) above or below the double bond.

Question 9

Give the Cahn-Ingold-Prelog priority rules

Answer 9

The atom with the higher atomic number on each of the C in the C=C is given the higher priority.
