How do you determine the hybridization of a steric number?
The steric number = the number of atoms bonded to the atom + the number of lone pairs the atom has.
If the steric number is 4, the atom is sp3 hybridized.
If the steric number is 3, the atom is sp2 hybridized.
If the steric number is 2, the atom is sp hybridized.
What is the steric number for ccl4?
The carbon atom is attached to two hydrogen atoms through single bonds, and to an oxygen atom through a double bond. Since no lone pairs are present, its steric number will be equal to 3.
What is the steric?
ChemistryScience. Steric number is the number of atoms bonded to a central atom of a molecule plus the number of lone pairs attached to the central atom. The steric number of a molecule is used in VSEPR (valence shell electron pair repulsion) theory to determine the molecular geometry.
How do I find my Vsepr number?
- VSEPR Rules:
- Identify the central atom.
- Count its valence electrons.
- Add one electron for each bonding atom.
- Add or subtract electrons for charge (see Top Tip)
- Divide the total of these by 2 to find the total.
- number of electron pairs.
- Use this number to predict the shape.
