Mechanism: Electrophilic Addition Electrophilic addition Alkenes undergo electrophilic addition reactions In an electrophilic addition reaction, two reactants form only one product So, elect...
Mechanism: Elimination In an elimination reaction, a small molecule is removed leaving behind an alkene This is another reaction of halogenoalkanes The halogenoalkanes are?heated?with?ethano...
Mechanism: Nucleophilic Substitution A?nucleophile?is an electron-rich species that can?donate?a pair of electrons ‘Nucleophile’ means ‘nucleus/positive charge loving’ as nucleophiles are at...
Mechanism: Free Radical Substitution Chain reactions A?free radical?is a species with one (or more than one) unpaired electrons The diagram shows a free radical which has one unpaired electr...
Interpreting a Mass Spectrum Mass spectroscopy?is an analytical technique used to identify unknown compounds The molecules in the small sample are?bombarded?with high energy electrons which ...
Elimination Reactions Elimination Reaction of Alcohols Alcohols can also undergo?dehydration?to form alkenes This is an example of an elimination reaction Elimination reactions involve a sma...
Combustion of Alcohols Combustion of alcohols Alcohols react with oxygen in the air when ignited and undergo?complete combustion?to form carbon dioxide and water alcohol + oxygen → carbon di...
Oxidation of Alcohols Oxidation of alcohols Primary alcohols can be oxidised to form?aldehydes?which can undergo further oxidation to form?carboxylic?acids Secondary alcohols can be oxidised to for...
Alcohol Production Alcohols?are compounds that contain at least one?hydroxy?(-OH) group The general formula of alcohols is?CnH2n+1OH Alcohols can be prepared by a wide range of chemical reac...
