Solution: Indicate which orbitals overlap to form the sigma bonds in:a. BeBr2b. HgCl2c. ICN

Solution: Indicate which orbitals overlap to form the sigma bonds in:a. BeBr2b. HgCl2c. ICN

Problem

Indicate which orbitals overlap to form the sigma bonds in:

a. BeBr2

b. HgCl2

c. ICN

Solution

We’re being asked to determine the orbitals that overlap to form sigma bonds in BeBr2, HgCl2, ICN.


Recall that σ (sigma) bonds are the single bonds in a molecule. They are formed from the end-on overlap of orbitals.



For this problem, we need to do the following steps:

Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the hybridization of the central atom.

Step 5: Determine the orbitals that overlap to form the sigma bonds.
