[11.4] isomerism

Question 1

what is isomerism?

Answer 1

different molecules with the same molecular formula are known as isomers

Question 2

what are structural isomers?

Answer 2

molecules with the same molecular formula but a different structure

Question 3

what are 3 types of structural isomers?

Answer 3

• chain isomers
• position isomers
• functional isomers

Question 4

what are chain isomers?

Answer 4

• caused by different arrangement of the carbon skeleton
• similar chemical properties (same functional group)
• slightly different physical properties
• more branching = lower boiling point

Question 5

what are position isomers?

Answer 5

• molecule has the same carbon skeleton
• molecule has the same function group but the functional group is in a different position
• similar chemical properties
• different physical properties

Question 6

what are functional isomers?

Answer 6

• molecules have the same molecular formula
• molecules have different functional groups
• different chemical properties
• different physical properties
