On Alcohols – Some High School level Chemistry

Alcohols are organic chemical compounds that consist of a hydroxyl group (-OH) attached to one or more carbon atoms within an alkane structure. Alcohols are a homologous series and have the general formula of CnH2n+1OH.

Examples of common alcohols include:

 

The OH attached within the alcohols result in higher melting and boiling points than expected for a compound of similar molecular mass. The hydroxyl group is a form of hydrogen bonding which is the strongest intermolecular force and gives rise to their stronger structure. This strong molecular structure takes more energy to break than the ones in compounds that are held together by London Dispersion Forces (weakest intermolecular force) or Permanent Dipole-Permanent Dipole attractions.
