Addition of HCI to 3-methyl-l-pentene gives two products. One of these is 2-chloro-3-methylpentane. What is the other product? answer: 3-chloro-3-methylpentane Please help me, I have a test tomorrow and I'm unsure of how to do this type of problem. I started out by drawing the molecule, but I seem to have added HCl worng.
