B. Understanding / Application / Analysis | |
- Explain what is isomers and isomerism by using butane.
- Explain why ethene gas can decolourises the acidified potassium mangante(II) solution but ethane can not decolourises acidified potassium mangante(II) solution.
- Explain why both hexane and hexane have six carbon atoms but hexene burns with a more sooty flame.
- Pentane and propane are members from alkane family. Explain why the melting point of pentane is higher than propane.
- Propanol and propanoic acid are dissolved in water. It is found that propanol solution is a neutral but propanoic acid is an acid solution.
- Explain the coagulation process of latex.
- Explain how to prevent coagulation of latex.
