Class 11 NEET Chemistry Chemical Bonding And Molecular Structure Part 1

(a) CO32−:6+24+2=32;sp2; trigonal planar
NO3−:7+24+1=32;sp2; trigonal planar
Hence, these are isoelectronic as well as isostructural.
(b) ClO3−:17+24+1=42;sp3, trigonal pyramidal
CO32−:6+24+2=32;sp2, trigonal planar
Hence, these are neither isoelectronic nor isostructural.
(c) SO32−:16+24+2=42;sp3, trigonal pyramidal
NO3−:7+24+1=32;sp2, trigonal planar
Theseare neither isoelectronic nor isostructural
(d) ClO3−:17+24+1=42;sp3, trigonal pyramidal
SO32−:16+24+2=42;sp3, trigonal pyramidal
Hence, these are isoelectronic as well as isostructural.
