Summary Of Year 11 Organic Chemistry

Question 0

List the families of hydrocarbons compounds.

Answer 0

• Alkanes
• Alkenes
• Cycloalkanes
• Cylocalkenes
• Aromatic

Question 1

What is fractional distillation ?

Answer 1

Separate the mixture of hydrocarbons from crude oil into “fractions” that have similar boiling points and molecular mass.

• catalytic cracking
• thermal cracking
• steam cracking

Question 2

List all properties of Alkanes.

Answer 2

• Saturated 
• Low Melting/ Boiling point
• Insoluble in water
-> only one which undergoes substitution reaction
• Combustion:
~Excess O2 = CO2
~Limited O2 = CO

Question 3

List all properties of Alkenes.

Answer 3

• unsaturated hydrocarbons
• cis and trans may occur as rotation can’t occur around the double bond
• Addition Reactions
• Combustion Reactions
