Question 1

What is a structural isomer?

Answer 1

Structural isomers have the same molecular formula but a different structural formula. They normally have similar chemical properties but their physical properties may be slightly different.

Question 2

What is a homologous series?

Answer 2

a series of compounds that can be grouped together based on similarities in their structure & reactions

Question 3

Physical properties of homologous series

Answer 3

• physical properties of a homologous series change gradually as the length of the carbon chain increases
• as length & amount of carbon atoms increase, the boiling point increase

Question 4

Answer 7

classes as arenes w ring structures consisting of alternating double & single carbon-carbon bonds

Question 8

What are isomers?

Answer 8
