- Carboxylic Acids
- Aldehydes/Ketones
- tetrahyrdridoboarte
- uses 2[H] per c-acid group
- and metals
- forms a carboxylate ion, to make a salt and hydrogen
- and water
- and carbonates
- reacts like a weak acid, to make carbon dioxide and water and a salt.
- and hydroxides
- makes a salt, and water.
- and alcohols
- can form esters
- must underdo acid or alkali hydrolysis
- acid (e.g. conc sulfuric acid)
- clean break into the c-acid and alcohol
- alkali (e.g. sodium hydroxide)
- forms the alcohol and a carboxylate salt.
- acid (e.g. conc sulfuric acid)
- alcohol goes at the beginning, c-acid at the end.
- must underdo acid or alkali hydrolysis
- catalyst: concentrated sulphuric acids. conditions- reflux
- can form esters
- NAMING
- add oic to the end
- NAMING SALTS
- PUT -OATE AT THE END. e.g. methanoic acid would make a methanoate salt.
- Aldehydes/Ketones
- dissolves to make a weak acid
- and water
- Chains of 1-4 carbons are very soluble, but any longer than that, the non-soluble carbon chain does not react with water, and reduces siolubility.
- TO TEST FOR
- tollens reagent (ammoniacal silver nitrate)
- will cause a silver mirror effect, distinguishing it from aldehydes.
- c-acids reduce the silver ion to make solid silver.
- will cause a silver mirror effect, distinguishing it from aldehydes.
