organic pka table

ORGANIC ACIDS AND BASES AND USING pKa VALUES : ( help!! please!!?

I need to find 3 bases that are capable of removing the most acidic hydrogen from methanol (CH3OH), ethylene (C2H2), and methylamine (CH3NH2). My problem is that I don’t have a good pKa table and to use the one in my book you need to know what exactly what you are looking for. Also, how do you know the pKa of the base and conjugate base since the pKa value only pertains to acids? I think I might be making it harder than it is but I’m really confused.

You need to find something that is not really acidic, which means its Ka is really small, so the conjugate base of this substance is really a strong acid.

Example, NH2(-), the amide ion, its conjugate acid is NH3, which is really a base, so as an acid, it will be really weak, making the amide ion very basic.

The CH3(-) ion is another very strong base, since its conjugate acid, CH4 is a terrible acid.

Either of this two substances are basic enough to remove protons from methanol, ethylene or methylamine.
