We are being asked to determine which central atom hybridization is expected in the series BH4-, CH4, and NH4+.
For this problem, we need to do these steps:
Step 1. Determine the central atom
Step 2. Calculate the total number of valence electrons present.
Step 3. Draw the Lewis Structure for the molecule
Step 4. Count number of electron domains around each central atom in the series to determine its hybridization
Which central atom hybridization would you expect in the series BH4-, CH4, NH4+?
