Determine the hybridization and the approximate bond angle of the labeled atom in the following molecule:

The image displays a structural diagram of an organic molecule annotated with arrows and labels. Here's a breakdown of the structure and annotations:

- There is a cyclohexane ring on the left side of the structure.
- Attached to the cyclohexane ring is an oxygen atom (O) with a lone pair of electrons indicated by two dots and labeled "a."
- Next to the oxygen, there is a sulfur atom (S) bonded to two hydrogen atoms (H) and featuring two lone pairs. This section is labeled "b."
- Following this, there is a carbon atom (C) with a double bond to another carbon (C:) with a lone pair, labeled "c" and "d" respectively.
- The carbon atom labeled "c" is also bonded to phosphorus (P), which is marked by an arrow labeled "e."
- The phosphorus atom is connected to the sulfur atom, forming part of the molecular framework, with its arrow labeled "f."

Each annotation (a, b, c, d, e, f) designates specific atoms and lone pairs within the molecular structure, demonstrating different functionalities and points of interaction within the molecule.

Expert Solution
Step 1

During hybridization, atomic orbitals of nearly equal energy combine to form an equal number of hybridized orbitals.

While finding hybridization, we only consider sigma bonds and lone pairs of the central atom.

Hence each single, double, triple bond, and lone pair is considered as a single electron density.

For 2 electron densities taken together, hybridization = sp.

For 3 electron densities taken together, hybridization = sp2.

For 4 electron densities taken together, hybridization = sp3.

For 5 electron densities taken together, hybridization = sp3d.

When there is no lone pair, bond angle is 180 for sp, 120 for sp2, and 109.28 for sp3.

Bond angle decrease from the above normal bond angles, where there is lone pair(s).
