Question:

(a) Which geometry and central atom hybridization would you expect in the series BH4-, CH4, NH4+?
(b) What would you expect for the magnitude and direction of the bond dipoles in this series?
(c) Write the formulas for the analogous species of the elements of period 3; would you expect them to have the same hybridization at the central atom?
