What is the reaction of 4-methyl-2-pentene with Cl2 and HBr?
Well, first figure out what is the most likely place on the molecule for a reaction to take place. Looking at the last “word” in the name, “2-pentene”, there is a double bond on the #2 carbon atom and looking at the beginning of the name, there is a methyl group on the #4 carbon. These are the two possible places for a reaction and a general rule is that, given the correct IUPAC name, if there is a functional group and a “ene” or “yne” ending to choose between, the main chain “ene” ending takes priority over the functional group (methyl). So, looking at a “skeleton” structural formula: CH3-CH=CH-CH-CH3 ——————-| (the dashes just line things up) ——————-CH3
the most likely place for the reaction is at the double bond. ——- Cl Cl ——- | —| (again dashes “-” are for alignment) CH3-C- C-CH-CH3
