WebbScore: 4.5/5 (12 votes) . This priority order is important in nomenclature as the higher priority group is the principle functional group and it is typically numbered such that is has the lowest number (the locant). You need to learn to recognise these functional groups not just for nomenclature but in order to recognise their reactions later.
