First point of difference rule

WebThe factors that influence the numbering according to the first point of difference rule are: the principal functional group is given the lowest possible locant substituents are then assigned locants based on this numbering scheme in such a way as to give the lowest locant number at the first time there is a difference WebThe locant is the number of the carbon atom to which the oxygen atom is bonded. If the oxygen is bonded to the middle carbon, the locant is 3. If the oxygen is bonded to an atom on either side (adjacent to an end carbon), the locant is 2 or 4; given the choice here, where the carbons are exactly equivalent, the lower number is always chosen.
