Question: Identify the hybridization of the central atom in NH3.

Options:

Correct Answer: sp3

Solution:

The nitrogen atom in NH3 is sp3 hybridized, forming three bonds and one lone pair.

Identify the hybridization of the central atom in NH3.

Identify the hybridization of the central atom in NH3.

Step 1: Identify the central atom in NH3, which is nitrogen (N).
Step 2: Count the number of bonds nitrogen forms in NH3. Nitrogen forms three bonds with three hydrogen (H) atoms.
Step 3: Determine if there are any lone pairs on the nitrogen atom. In NH3, nitrogen has one lone pair.
Step 4: Add the number of bonds (3) to the number of lone pairs (1). This gives a total of 4 regions of electron density.
Step 5: Use the total number of regions of electron density to determine hybridization. 4 regions correspond to sp3 hybridization.

Hybridization – The concept of hybridization involves the mixing of atomic orbitals to form new hybrid orbitals that can accommodate bonding and lone pairs.
Molecular Geometry – Understanding how the arrangement of bonds and lone pairs around a central atom determines the molecular shape.
