Question: Which molecular geometry is associated with a molecule that has two bonding pairs and two lone pairs of electrons?

Options:

Correct Answer: Bent

Solution:

A molecule with two bonding pairs and two lone pairs adopts a bent geometry due to the repulsion of the lone pairs.

Which molecular geometry is associated with a molecule that has two bonding pairs and two lone pairs of electrons?

Step 1: Identify the number of bonding pairs and lone pairs in the molecule. In this case, there are 2 bonding pairs and 2 lone pairs.
Step 2: Understand that bonding pairs are the pairs of electrons that are shared between atoms, while lone pairs are the pairs of electrons that are not shared.
Step 3: Recognize that lone pairs take up more space than bonding pairs because they are only associated with one atom.
Step 4: Determine the molecular geometry based on the arrangement of bonding pairs and lone pairs. With 2 bonding pairs and 2 lone pairs, the shape is affected by the repulsion of the lone pairs.
Step 5: Conclude that the molecule adopts a bent geometry because the lone pairs push the bonding pairs closer together, creating an angle that is less than 180 degrees.
