Predict the shape and polarity of each of the following molecules. Assume all bonds are polar: a) a central atom with four identical bonded atoms and no lone pairs. b) a central atom with three identical bonded atoms and one lone pair. c) a central atom with four bonded atoms that are not identical and no lone pairs.
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
