Maximum bond angle is present in : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the shape and hybridization of BBr3, BCl3, and BF3. All three are boron trihalides where boron is sp2-hybridized with zero lone pairs. Step 2: This gives all three molecules a perfectly symmetrical trigonal planar geometry, meaning they all have a bond angle of exactly 120°. Step 3: Since all of them have the same maximum bond angle of 120°, 'none of these' is the correct choice, which corresponds to option (d).
