i keep getting confused with reactions where halogens are added.
i thought when a halogen (ie. Br2) + UV light is added to something - the halogen attaches to the least substituted atom.....
but sometimes it doesn't, it adds to the most substituted.....
Is it different depending onthe whether the molecule is an alkene/a ring/ etc?
can someone clarify this?? ill try to go find some exact examples in the meantime....
