Q: What is the molecular shape of a molecule with the formula AX3E?
Solution: AX3E indicates three bonding pairs and one lone pair, resulting in a trigonal pyramidal shape.
Steps: 4
Step 1: Identify the formula AX3E. Here, 'A' is the central atom, 'X' represents the atoms bonded to 'A', and 'E' represents a lone pair of electrons on 'A'.
Step 2: Count the number of bonding pairs. In AX3E, there are 3 'X' atoms, which means there are 3 bonding pairs.
Step 3: Count the number of lone pairs. In AX3E, there is 1 'E', which means there is 1 lone pair.
Step 4: Determine the molecular shape based on the number of bonding pairs and lone pairs. With 3 bonding pairs and 1 lone pair, the shape is trigonal pyramidal.
