The pair of species with similar shape is : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the geometry of each pair of species using VSEPR theory. Step 2: PCl3 and NH3 both have 3 bond pairs and 1 lone pair on the central atom (steric number = 4), which gives them both a trigonal pyramidal shape. Step 3: Since both have the same pyramidal shape, they represent the pair with similar shape.
