Which of the following pairs of ions are isoelectronic and isostructural? [NCERT Exemplar] |
| Answer» OPTION DEXPLANATION:Isostructural chemical compounds have similar chemical structures. ISOELECTRONIC terms refer to two atom, ions or molecules that have the same number of valence electrons. ClO 3 − =SO 3 2− Number of electrons- CO 3 2− =6+2+24=32 SO 3 2− =16+2+24=32 ClO 3 2− =17+24+1=42 NO 3 2− =7+2+24=33 Hence, ClO 3 2− and SO 3 2− are isoelectronic and pyramidal in shape. Option D is the CORRECT answer. | |
