- Alcohols, Carboxylic acids and Esters.
- Alcohols
- The alcohols are a homologous series of organic compounds.
- They all contain the functional group –OH.
- This group is responsible for the properties of alcohols.
- The names of alcohols end with ‘-ol’ – eg ethanol.
- alcohols are highly flammable, making them useful as fuels.
- They are also used as solvents in marker pens, medicines, and cosmetics
- Carboxylic acids
- The carboxylic acids are a homologous series of organic compounds.
- They all contain the same functional group –COOH.
- The names of carboxylic acids end in ‘-oic acid’ – eg ethanoic acid.
- Vinegar is an aqueous solution containing ethanoic acid
- Ethanoic acid is formed from the mild oxidation of the ethanol
- Esters
- Esters are a group of organic compounds which all contain the functional group –COO–.
- they are volatile - they are liquids that become vapours easily
- they have distinctive ‘fruity’ smells
- These properties make esters very useful as food flavourings, and as perfumes in cosmetics.
- Some esters are obtained from natural sources, such as fruits. Others are manufactured.
- Excess ethanoic acid in the reaction mixture is neutralised with sodium hydrogencarbonate
- The first part of an ester’s name comes from the alcohol - it ends with the letters 'yl'. The second part of its name comes from the carboxylic acid - it ends with the letters 'oate'.
- Esters are a group of organic compounds which all contain the functional group –COO–.
- Alcohols
