Carboxylic Acids Describe the properties of aqueous ethanoic acid● Ethanoic acid is a member of the carboxylic acids, they have the functional group –COOH.● It dissolves in water to produce an acidic solution (Extended only) Describe the formation of ethanoic aci● First four members are: methanoic acid, ethanoic acid, propanoic acid and butanoic acid Describe the formation of ethanoic acid by the oxidation of ethanol by fermentation and with acidified potassium manganate(VII)● Ethanol reacts with oxygen in the air to form ethanoic acid (microbial oxidation)● Ethanol reacts with acidified potassium manganate(VII) to form ethanoic acid Describe ethanoic acid as…● A typical weak acid● this means ethanol will release some H+ ions in solution, but will not fully dissociate (loses the H + from the COOH group)● Carboxylic acids react with alcohols in the presence of an acid catalyst toproduce esters…o They have the functional group –COO-.www.pmt.education● name:o first part is from alcohol e.g. methanol → methylo second part is from carboxylic acid e.g. butanoic acid→ butanoate Esters with Methanoic acid: Esters with Ethanoic acid: Esters with propanoic acid:
