Alkenes outcomes6 objectives
- Identify that alkenes contain a double bond between carbon atoms and classify them as unsaturated hydrocarbons.
- Explain how alkenes and hydrogen are produced through the cracking process of larger alkane molecules, which involves high temperatures and a catalyst.
- Discuss the motivations behind the cracking of larger alkane molecules.
- Outline the method to differentiate between saturated and unsaturated hydrocarbons using their reaction with aqueous bromine.
- Recognize that an addition reaction results in the formation of a single product.
- Explain the characteristics of alkenes based on their addition reactions with: (a) bromine or aqueous bromine, (b) hydrogen in the presence of a nickel catalyst, and (c) steam with an acid catalyst, including drawing the structural or displayed formulae of the resulting products.
