This has a purple dye added so less attractive to drink. ReactionsReacts with Sodium – like it does with water, but not as vigorous. Oxidation – An alcohol is oxidised to a carboxylic acid when boiled with potassium dichromate (VI) solution. So ethanol can be oxidised to ethanoic acids (e.g. alcohol left out smells like vinegar)

16 I can name and give the formula for some organic chemicals. Grade C I can draw the structure for some organic chemicals. Grade B I can explain the differences between organic chemicals. Grade A Keywords: Alkane, Alkene, Alcohol, Carboxylic Acid, Esters, Carboxylic Acids These are ____________________ substances that _____________ dissolve in water. They also behave like other acids, for example: Ethanoic acid + sodium carbonate  __________ + __________ + _________ Carboxylic acids are ______________ acids and have a pH around __________. For these to have acidic properties, they must first ____________________________________________. By doing this, the water causes the acid to ________________ and their molecules split up to form a ___________ and ______________ ions. The ____________ ion is common in all acid. Example with hydrochloric acid (symbol equation): ________  ________ + _________ acidicdo Sodium ethanoate water Carbon dioxide weak 3 Dissolve in water ionise positive negative H+ HClH+Cl-

Grade A Keywords: Alkane, Alkene, Alcohol, Carboxylic Acid, Esters, Strong v Weak Acids Strong acids _________________________ ionise in water. Weak acids __________________________ ionise in water. Therefore, the strong acid will have a greater concentration of ____________ ions and so a __________ pH than the weak acid. Completely Partially H+ lower

Grade A Keywords: Alkane, Alkene, Alcohol, Carboxylic Acid, Esters, Making Esters Carboxylic acids also react with ___________________ to form esters. ______________ is also formed in this reversible reaction. As a catalyst _____________________________________ is used. An example is: Ethanoic Acid + ethanol ethyl ethanoate + water What would be produced in: Ethanoic acid + methanol The general formula is: Carboxlylic acid + alcohol ester + water alcohols Water Sulphuric acid Methyl ethanoate + water
