E. trigonal pyramidal

CramX · Accepted Answer

Step 1: Let's solve this step by step:. Step 2: : Determine the Lewis structure. - Silicon (Si) has 4 valence electrons - Oxygen (O) has 6 valence electrons Step 3: : Electron Pair Geometry. - Silicon is the central atom - Two oxygen atoms are bonded to silicon - Electron configuration around silicon follows the octet rule - Total electron domains: 4 (2 bonding pairs, 0 lone pairs) Step 4: : VSEPR Theory Analysis. - With 4 electron domains arranged symmetrically around the central atom - No lone pairs on the central atom - Bonds are equally distributed in three-dimensional space Step 5: : Molecular Geometry Determination. - 4 electron domains with no lone pairs results in a tetrahedral geometry - All bonds are equivalent and point to the corners of a tetrahedron Final Answer: Explanation: SiO₂ has a tetrahedral molecular geometry due to its symmetric arrangement of oxygen atoms around the central silicon atom, with no lone pairs present.
