CnH2n 2 of 26 What is there none of unlike alkanes? No rotation about the double bond 3 of 26 What is a Z isomer? The CH3 groups are on the same side 4 of 26 What is an E Isomer? When they are opposite 5 of 26 What is Geometric isomerism? It is a form of Stereoisomerism 6 of 26 What is the definition of Stereoisomerism? The same structural formula but the bonds are arranged differently in space 7 of 26 What are the only intermolecular forces between the alkene molecule? Van der Waal forces 8 of 26 What happens with the BP and MP as the carbon atoms increase? They increase 9 of 26 What are alkenes like in water? Not soluble 10 of 26 What are alkenes like with alkanes? They are more reactive 11 of 26 What does the C == C form? An electron rich area of the molecule 12 of 26 What can happen to this molecule? Attacked by positively charged reagants 13 of 26 What are these reagents called? Electrophiles 14 of 26 What is the definition of an electrophile? An electron acceptor 15 of 26 What mechanism do alkenes undergo? Electrophillic addition reaction 16 of 26 What is the equation for the combustion of Alkenes? CH2=CH2 + 3O2 --> 2CO2 + 2H20 17 of 26 What is a Polymer? A long chain molecule made from lots of small molecules joining together 18 of 26 What is a monomer? small molecules that join together to make polymers 19 of 26 What is addition polymerisation? ormation of large chain molecules from lots of small molecules joining joining with no other product 20 of 26 What is the repeating Unit? The smallest group of atoms that produce the polymer when repeated over and over again 21 of 26 What are plastics? Not biodegradable 22 of 26 How can we dispose of plastic? We use it or recycle it 23 of 26 What is the first step of mechanical recycling? Seperate the different types of plastic 24 of 26 What happens after they are sorted? Washed and they may be ground into small pieces 25 of 26 What happens to these small pieces? They are melted and remoulded 26 of 26
