Among the following species, the least angle around the central atom is in : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the bond angle of each species: O3 is bent (~117°); I3^- is linear (180°); NO2^- is bent (~115°); PH3 is pyramidal (~93.6°) using almost pure p-orbitals. Step 2: Compare the angles: 93.6° (PH3) < 115° (NO2^-) < 117° (O3) < 180° (I3^-). Step 3: Therefore, the least bond angle is in PH3, which corresponds to option (d).
