Work Step by Step
a. V-shaped (bent) molecular structure
- Can occur with either trigonal planar or tetrahedral electron-pair arrangements.
- Trigonal planar arrangement: central atom is sp² hybridized.
- Tetrahedral arrangement: central atom is sp³ hybridized.
b. See-saw structure
- Arises from a trigonal bipyramidal electron-pair arrangement.
- Central atom requires dsp³ hybridization.
c. Trigonal pyramid structure
- Occurs when the central atom has three bonded atoms and one lone pair.
- With four effective electron pairs (tetrahedral electron-pair geometry), the central atom is sp³ hybridized.
d. Trigonal bipyramidal electron-pair arrangement
- Requires dsp³ hybridization.
e. Tetrahedral electron-pair arrangement
- Requires sp³ hybridization.
