Question

If M is element of actinoids series, the degree of complex formation decreases in the order.

• A. $M^{4+}>M^{3+}>MO_2^{2+}>MO_2^+$
• B. $M^{4+}>MO_2^{2+}>M^{3+}>MO_2^+$
• C. $MO_2^{2+}>MO_2^+>M^{3+}>M^{4+}$
• D. $MO_2^{2+}>MO_2^+>M^{4+}>M^{3+}$

Answer 1

Answer: (B)

$M^{4+}>MO_2^{2+}>M^{3+}>MO_2^+$

Answer 2

The correct option is (B): $M^{4+}>MO_2^{2+}>M^{3+}>MO_2^+$.
