WebThe priority list of the functional group can be given as: -COOH > -SO 3 H > -COOR (R= alkyl group) > -COCl > -CONH 2 > -CN > -HC=O > >C=O > -OH > -NH 2 > >C=C< > -CC- Functional groups like -R, C 6 H 5 -, halogens (F, Cl, Br, I), -NO 2, alkoxy (-OR) etc., are always used as prefix substituents. WebExample: but-2-ene. Isomer 1 : Step 1 : split the alkene. Step 2 : assign the relative priorities. The two attached atoms are C and H, so since the atomic numbers C > H then the -CH3 group is higher priority. Step 3 : look at the relative positions of the higher priority groups : same side = Z, hence (Z)-but-2-ene. Isomer 2 : WebJan 23, 2024 · Rule 1.

WebFunctional groups have different priorities when it comes to naming. They are assigned priorities based broadly on their reactivity. So for example a carboxylic acid will have a higher priority than an alkene or alkyne. The highest priority functional group will be the molecule's overall suffix and will determine the class of the molecule.
