Task 2: For the reactions below: Write a balanced equation. Draw the reaction mechanism. Justify the species involved as nucleophiles, electrophiles, radicals, acids or bases. Justify the reaction as an addition, substitution, elimination, or condensation. For the substitutions and elimination reactions predict whether the reaction is likely to be SN1,SN2,E1 or E2 with a brief justification. Bromine and Propene Bromobutane with aqueous sodium hydroxide at room temperature Chlorine with methane in the presence of UV light Methanol and ethanoic acid heated under reflux with concentrated sulphuric acid. A mixture of HCN and KCN with bromoethane. 2-bromo-2methylbutane with hot ethanoilc potassium hydroxide. Ammonia with 2-bromo-2-methylpropane. Propan-2-ol heated with concentrated sulphuric acid. Task 3: Some reactions produce “unexpected” products due to rearrangements. Give an example of a rearrangement, including a reaction mechanism to show how this occurs. Task 4: Draw and explain the energy profiles for “two “different reactions, at least one which involves a transition stage.
