Question Analysis
This question involves VSEPR theory. The main focus is on applying the theory to determine the molecular geometry of a given molecule.

Key Concept Explanation
According to VSEPR theory, electron pairs around a central atom repel each other and arrange themselves as far apart as possible to minimize repulsion.
The molecular geometry depends on: 1. The number of electron domains (bonding + lone pairs). 2. Whether lone pairs are present.

Step-by-step Solution
1. Identify the central atom: Silicon (Si) is the central atom because it is less electronegative than Chlorine.
2. Determine valence electrons: Si: 4 valence electrons. Cl: 7 valence electro...
