free radical substitution
for alkanes only
produce hydrogen halide
each halogen molecule only substitute out one hydrogen
uv/heat needed
combustion
complete combustion = carbon dioxide + water
incomplete combustion = carbon monoxide / carbon + water
addition reaction - hydrogenation
for alkenes only
require Ni catalyst and heat
no additional products
addition of halogens
for alkenes only
no requirement for catalyst
no additional products
alcohols forms
water (steam) added to a double bond
sulphuric acid catalyst
test for saturation
add bromine solution see if there is colour change from brown to colourless
addition polymerisation
addition between alkene monomer units
catalyst needed
oxidation of alcohols
using oxidising agent (catalyst):
acidified dichromate H+&Cr2O72-
acidified permanganate H+&MnO4-
oxygen (natural oxidation)
distillation → aldehyde →reflux → carboxylic acid
reflux → ketone
no reaction
esterification
alcohol + carboxylic acid →(acid) ester + water
substitution - halogenoalkane to alcohol
via nucleophilic substitution reactions
nucleophile = lone pair donor e.g. (OH-)
electrophile = electron/lone pair acceptor
electrophilic substitution reactions of benzene
benzene + halogen → (heat & Fe(Hal)3) halogenobenzene
nitration
benzene + HNO3 → (H2SO4 & heat) nitrobenzene
