WebRyan W. 3 years ago. Halogens and alkyl chains are equal in priority. The rule that matters is that you use the set of numbers with the lowest number at the first point of difference. 2,5,5 vs 3,3,6. 2 is lower than 3. 2,5,5 is the correct way to number the chain, so 5-bromo-2,5-dimethylheptane is the correct name. WebThe first thing you need to do is determine the number of the groups that are on each atom. By groups, we mean either atoms or lone pairs of electrons. This is also known as the Steric Number (SN). Below are a few examples of steric numbers 2-4 which is largely what you need to know in organic chemistry: WebAcceptable names for this molecule include 3-methylhex-2-ene and 3-methyl-2-hexene. IUPAC rules encourage placing the location identifier close to the feature at that location. The first name follows IUPAC rules to the letter. However these names can seem awkward even to chemists, and the second form is used frequently. fortnite aim cheat not detected
