ChemistryAlcoholsA2/A-levelAQA Created by: Rachael1Created on: 26-04-17 18:51 What's alcohol mainly made up of? ethanol 1 of 15 What's alcohol used for? sterilising, solvents, fuels and reactants 2 of 15 What are the two ways of making alcohol? fermentation of yeast and hydration of ethene 3 of 15 What catalyst is used in hydration of ethene to produce an alcohol? phosphoric acid 4 of 15 What's the catalyst used to produce an alkene from an alcohol? sulfuric acid 5 of 15 What is a biofuel? renewable fuel made from plants 6 of 15 What type of process is hydration of ethene? electrophilic addtion 7 of 15 Why is it useful to turn alcohols into alkenes? produce plastics without having to use crude oil- use a renewable biofuel 8 of 15 When alcohols turn into other organic compounds, what is removed from where? A H is removed from carbon and oxygen 9 of 15 What do primary alcohols oxidise to produce? aldehyde and carboxylic acid 10 of 15 What do secondary alcohols oxidise to produce? ketones 11 of 15 How do we know if an alcohol is primary, secondary or tertiary? depends on the number of bonds between carbon atoms e.g. if there's a double bond between two carbon atoms=secondary 12 of 15 What are the oxidising agents used to oxidise these alcohols? K2C2O7/H+ acidified potassium- orange to green, Fehling's reagent- blue alkaline solution copper (11) ions to copper (1) oxide brick red, Tollens'- silver amine complex- silver mirror 13 of 15 Does an aldehyde have a lower or high melting point than an alchol? lower because no hydrogen bonding involved 14 of 15 What does this (o) mean? 1 mole of oxygen from oxidising agent 15 of 15
