Q: Which of the following molecules has a bent shape according to VSEPR theory?
Solution: H2O has two bonding pairs and two lone pairs, leading to a bent molecular geometry.
Steps: 6
Step 1: Understand that VSEPR theory helps predict the shape of molecules based on the number of bonding pairs and lone pairs of electrons around a central atom.
Step 2: Identify the molecule in question, which is H2O (water).
Step 3: Count the number of bonding pairs in H2O. There are 2 hydrogen atoms bonded to the oxygen atom, so there are 2 bonding pairs.
Step 4: Count the number of lone pairs on the central atom (oxygen) in H2O. Oxygen has 2 lone pairs of electrons.
Step 5: Combine the bonding pairs and lone pairs. H2O has 2 bonding pairs and 2 lone pairs.
Step 6: Use VSEPR theory to determine the shape. With 2 bonding pairs and 2 lone pairs, the shape is bent.
