describe the mechanism of electrophilic addition in alkenes, using bromine/ethene and hydrogen bromide/propene as examples
describe and explain the reactions of halide ions with: (a) aqueous silver ions followed by aqueous ammonia (the formation and formula of the \([Ag(NH_3)_2]^+\) complex is not required) (b) concentrated sulfuric acid, to include balanced chemical equations
recall the reaction (reagents and conditions) by which esters can be produced: (a) the condensation reaction between an alcohol and a carboxylic acid with concentrated \( H_2SO_4 \) as catalyst
