Uni-structural Use the link to help you identify common features of alkenes Also use page 126 in your text book
Multistructural Use the link to help you work out the shape of alkene molecules Write your response down in terms of bond angles and the reasons for the bond angles
Multistructural Describe the nature of the double bond. You must mention sigma and pi bonds, what they are and how they are formed
Relational Same video as before, in addition use page 128 of your text book to support. Describe and explain what happens when an alkene reacts, what the bond enthalpies show, the differences inb strength between a sigma and a pi bond
Relational Find out what type of reaction causes halogens and hydrogen to react with alkenes. Explain why these reactions happen. Also use page 128 and 129 to add examples to your response.
Extended abstract Try and predict the reaction mechanism that occurs when HBr and ethene react. Things to think about; What is the product? What are the characteristics of a double bond? Does hydrogen bromide have a ‘perfect’ covalent bond (think electronegativites) Heterolytic or homolytic fission? Find out what curly arrows mean! Please do not worry if you don’t complete this activity, we will be covering it in more detail next lesson.
