Alcohols
The alcohols are another homologous series of compounds that have the general formula CnH2n+1OH.




The
easy way to work it out is the number of carbon atoms
bonded to the COH group. A primary alcohol has 0 or 1 carbon on the COH. The
secondary alcohol has 2 carbons…

Combustion

Alcohols burn in a plentiful supply of oxygen to produce carbon dioxide and water vapour.

With sodium

Sodium sinks in ethanol (as it is more dense) and this results in the formation of hydrogen
gas and sodium ethoxide. Ethanol acts as an acid in this reaction.

Substitution

Alcohols react…

Halogenoalkanes
Nucleophilic Substitution
Halogenoalkanes contain a polar bond on the functional group, because the halogen is
electronegative so becomes - and the carbon is positive. This means it is susceptible to
nucleophillic attack by ions.
The strength of the C - Halogen bond also influences the rate of substitution. The…
