Question

Assertion :Statement $-$ 1 : Coordination isomerism occurs when both cation and anion are complex. Reason: Statement $-$ 2 : The complexes with coordination number 6 form octahedral complexes involving either $s{p}^3{d}^2$ or $d^{2}s{p}^3$ hybridization.

• A. Statement $-$ 1 is true, Statement $-$ 2 is true and Statement $-$ 2 is correct explanation for Statement $-$ 1.
• B. Statement $-$ 1 is true, Statement $-$ 2 is true and Statement $-$ 2 is NOT the correct explanation for Statement $-$ 1.
• C. Statement $-$ 1 is true, Statement $-$ 2 is false.
• D. Statement $-$ 1 is false, Statement $-$ 2 is true.

Answer 1

The correct option is B Statement $-$ 1 is true, Statement $-$ 2 is true and Statement $-$ 2 is NOT the correct explanation for Statement $-$ 1.

The complexes with coordination number 6 form octahedral complexes and to form complex they need six orbital and for this, they form complex either by $d^{2}s{p}^{3}ors{p}^3{d}^2$ hybridization.
