naming system name
IUPAC
strategy for naming molecules
-identify parent (longest carbon chain or ring)
-identify suffix (highest priority group)
-assign the locants (carbon numbers)
-name substituents give locant and prefix (di, tetra for how many locants)
-assemble the name
Give the order of how we name
-substituents- front (other func groups)
-parent- middle- with greek prefix
-suffix- end- highest pri group, locant is position of func group on chain
naming parent (state prefixes and ring name)
-meth, eth, prop, but, pent, hex,hept,oct,non,dec
-cyclo for ring
-yl ending for simple alkanes
-an with func groups
-an with func groups
locant
-location of substituent on parent structure
-highest func group has lowest number
-alphabetical for eg ethyl, methyl etc
subsitutents
-not highest priority
branched alkane substituents
- isopropyl- 2 branched
-sec-butyl- 3 branched
-isobutyl- extrabranch-3 branched
-tert-butyl- tertiary- 3 branched

naming alkenes and alkynes
-alkynes- suffix yne
alkenes- suffix ene
-func groups that are higher: add en/yn before family suffix along with locant
lower: after
