As boiling point decreases, volatility increases. 1 of 14 Oxidation When oxygen is added to a molecule. 2 of 14 Oxidising agent Acidified potassium dichromate 3 of 14 Reflux Used to make primary alcohols into carboxylic acids or secondary into ketones. 4 of 14 Distillation Used to make primary alcohols into aldehydes or secondary into ketones. 5 of 14 Ester Formed when an alcohol and carboxylic acid react. -(C=O)-O-(CH2)- 6 of 14 Esterification Reaction between alcohol with a carboxylic acid to produce ester and water. 7 of 14 Dehydration Is an elimination reaction in which water is removed from a saturated molecule to make an unsaturated molecule. 8 of 14 Hydrolysis Is the reaction with water or aqueous hydroxide ions that breaks a chemical bond into two compounds. 9 of 14 Percentage yield Found by moles product/moles of reactant x100. 10 of 14 Atom economy Mr of desired product/Mr of all products x100 11 of 14 IR spectroscopy Shows the absorption of IR radiation by bonds to show what bonds are present in a sample 12 of 14 Mass spectrometry Shows the mass/charge for fragments of a molecule 13 of 14 MS fragment A piece of the molecule broke in MS. Allows us to piece together the starting molecule. 14 of 14
