Which of the following has a bond angle of approximately 120 degrees?

Which of the following has a bond angle of approximately 120 degrees?

Step 1: Understand what a bond angle is. A bond angle is the angle between two bonds that are connected to the same atom.
Step 2: Learn about molecular geometry. Different shapes of molecules have different bond angles.
Step 3: Identify the shape of BF3 (Boron Trifluoride). BF3 has three fluorine atoms bonded to one boron atom.
Step 4: Recognize that BF3 has a trigonal planar shape. This means the three bonds are spread out evenly around the boron atom.
Step 5: Know that in a trigonal planar shape, the bond angles are approximately 120 degrees.
