WM 2- carboxylic acids 0.0 / 5 ? ChemistryFunctional GroupsASOCR Created by: anabobCreated on: 22-01-18 20:54 what is a phenol? a benzene ring with an -OH group 1 of 10 which equation demonstarates the -OH group reacting with water? R-OH + H2O = R-O- + H3O+ 2 of 10 which equation demonstrates waters abiloty to behave as a weak acid? H-OH + H2O = H-O- + H3O+ 3 of 10 place carboxylic acid, water, alcohol and phenol in order of increasing acid strength alcohol 4 of 10 what are phenols and carboxylic acids strogn enough acids to do? react with strong bases (eg NaOH) to form salts 5 of 10 how can you differentiate between carboxylic acids and phenols? c.a react with Na2CO3 to form sodium salt of acid - the reaction with carbonate fizzzes, producing CO2 so can be identified. 6 of 10 how are phenols tested for ? give purple colour with neutral iron (III) chloride solution as they form a complex 7 of 10 how can phenols make esters? react with acid anhydride under alkaline conditions to make ester and carboxylic acid 8 of 10 what are two ways of esterifying salycilic acid? phenol OH group reacts with acid anhydride _cooh group can react with an alcohol 9 of 10 what is formed in either way of esterifying salycilic acid? esterifying phenol OH- forms aspirin, reacting COOH with methanol- oil of wintergreen 10 of 10
