Which of the following pairs of ions are isoelectronic and isostructural? (i) CO32-, NO3- (ii) ClO3- , CO32- (iii) SO32-, NO3- (iv) ClO3- , SO32–Solution:
Option 1) NO–3 and CO32− are isoelectronic as both have the same numbers of electrons. Nitrate (NO–3) has 32electrons. Carbonate (CO32) has 32electrons. NO–3 and CO32− are isostructural as both have similar chemical structures-trigonal planar
