  • All straight-chained alkanols have the suffix ‘-anol’:
    • ‘an’ denotes all single bonds between carbon atoms.
    • ‘ol’ denotes the presence of a hydroxy (OH) group.
  • When there is more than one possible position for the hydroxy group, a number denotes which carbon atom has the hydroxy group attached.
