Question Analysis
This question tests the student's knowledge of molecular geometries and their corresponding bond angles.

Key Concept Explanation
The bond angle of 109.5 degrees is characteristic of a tetrahedral molecular geometry. Molecules with this geometry include those with four bonding pairs and no lone pairs.

Option Analysis
A. BeCl₂ has a linear geometry with a bond angle of 180 degrees.
B. BF₃ has a trigonal planar geometry with a bond angle of 120 degrees.
C. CH₄ has a tetrahedral geometry wi...
