Questions & Step-by-Step Solutions
Which of the following molecules has a trigonal planar geometry?
Step 1: Understand what trigonal planar geometry means. It refers to a shape where three atoms are arranged around a central atom, all in the same plane, forming a triangle.
Step 2: Identify the molecule in question, which is BF3 (Boron Trifluoride).
Step 3: Count the number of bonding pairs in BF3. Boron (B) is bonded to three fluorine (F) atoms, so there are three bonding pairs.
Step 4: Check for lone pairs on the central atom (Boron). In BF3, Boron has no lone pairs.
Step 5: Since BF3 has three bonding pairs and no lone pairs, it has a trigonal planar geometry.
