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.
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
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
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.
