Question

Which of the following pairs of ions are isoelectronic and isostructural ?

Options

A.ClO₃⁻, CO₃²⁻

B.SO₃²⁻, NO₃⁻

C.ClO₃⁻, SO₃²⁻

D.CO₃²⁻, SO₃²⁻

Solution

                                        ClO₃⁻      SO₃⁻²
No. of e⁻                          42            42
hybridisation                   sp³          sp³
both are having one lone pair on central atom hence they are pyramidal.
