Amongst NO3^-, AsO3^3-, CO3^2-, ClO3^-, SO3^2- and BO3^3-, the non-planar species are : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the geometries of the given anions. Step 2: NO3^-, CO3^2-, and BO3^3- are sp2 hybridized with 3 sigma bond pairs and 0 lone pairs, giving them a planar (trigonal planar) geometry. AsO3^3-, ClO3^-, and SO3^2- are sp3 hybridized with 3 bond pairs and 1 lone pair on the central atom, giving them a pyramidal (non-planar) shape. Step 3: Consequently, the non-planar species are AsO3^3-, ClO3^-, and SO3^2-, corresponding to option (b).
