Can you type these out? The slides don't seem to want to download for me. In any event, what would your thoughts be on the questions?

Those question can be answered if you look at the third from last slide.  If you'd read your own handout and tried to do your own homework you might've known that. 
Go and do some work yourself and come back with any queries but remember we are not here to do your work for you.

Hello

the important bit to know is that transitions of electrons from bonding to antibonding orbitals in conjugated double bonds needs more energy or a shorter wavelength to be promoted from a low energy orbital to a higher energy orbital in contrast to electrons in non-bonding orbital where the electrons are higher in energy and need less energy (longer wavelength) to be promoted.
So my tip to be you is that you are looking for a lone pair in a sp or sp2 hybridized orbital as a result of pH 11 and secondly what is the chlorine (electronegativity) influence on this lone pair……..delocalization and secondly you will need to understand why a given compound has the pKa value it does.

hope it helps
