On haloalkanes, does branching affect polarity? I know 2-bromo-2-methylpropane is more polar that 1-chlorobutane, but why?

Typically, the more branching, the higher the polarity. That’s because the more branches you have, the more interactions you can have with water! You’re increasing the number of atoms that can interact with the hydrophilic environment. Hope this helps!
