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)

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-
