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
