Question Analysis
This question involves VSEPR theory. The main focus is on recalling the characteristic bond angle associated with a tetrahedral molecular geometry.

Key Concept Explanation
In VSEPR theory, a tetrahedral geometry occurs when there are four electron domains around the central atom with no lone pairs. This arrangement minimizes repulsion by placing the bonding pairs as far apart as possible in three-dimensional space. The ideal bond angle for a tetrahedral geometry is approximately 109.5°.

Step-by-step Solution
1. A molecule with a tetrahedral geometry has an ideal bond angle of 109.5 degrees. Ther...
