• alcohols have the general formula CnH2n+1OH
• all alcohols have the functional group hydroxyl (-OH) and have the ending -ol. eg propanol
• alcohols - as the number of carbons increases the solubility decreases
• all carboxylic acids contain the functional group carboxyl (-COOH) and have the ending - oic acid. Eg. propanoic acid
• the longer the carbon chain length, the more insoluble it is in water
• carboxylic acids have the general formula CnH2n+1COOH
• when carboxylic acids are reacted to form a salt the salt has the same first part of the name but instead of -oic acid it becomes - oate. Eg - pentanoic acid -> pentanoate
• methanoic, ethanoic, propanoic and butanoic acid are considered to be miscible in water - they can be mixed together
