This question is about hydrocarbons. Hexane and hexene are hydrocarbons containing six carbon atoms in each molecule. Hexane is an alkane and hexene is an alkene.
a.[2]
Identify the molecular formula of hexane and hexene from the following options:
- C6H10\text{C}_6\text{H}_{10}C6H10
- C6H12\text{C}_6\text{H}_{12}C6H12
- C6H14\text{C}_6\text{H}_{14}C6H14
- C6H16\text{C}_6\text{H}_{16}C6H16
b.[2]
Bromine water is added to separate samples of hexane and hexene in the absence of UV light. What would be observed when bromine water is added to:
- Hexane
- Hexene
c.[6]
Ethane is an alkane and ethene is an alkene. Figure 1 shows the displayed structural formulae of ethane and ethene.
Compare ethane with ethene. You should refer to:
- their structure and bonding
- their reactions.
