Isomers

Question 1

What are the types of isomerism? (3)

Answer 1

• Functional group isomerism
• Chain isomerism
• Positional isomerism

Question 2

Define functional group isomerism.

Answer 2

These molecules have the same molecular formula but different functional groups.

Question 3

Define chain isomerism.

Answer 3

These molecules have the same molecular formula but their chain lengths differ.

Question 4

Define positional isomerism.

Answer 4

These molecules have the same molecular formula but the position of the functional group on the main chain is different.
