Question

Find the correct statement.

i) Magnetic moment $M{n}^{2+}$ ion is $\sqrt{35}$

ii) $T{i}^{4+}$ is exhibit purple color

iii) 1 Bohr Magneton=$9.273\times {10}^{-24}$Tesla ${}^{-1}$

iv) Secondary valency of transition metal ion is equal to its co-ordination number

• A. Only i is correct
• B. Only ii is correct
• C. i,iii,iv are correct
• D. All are correct

Answer 1

The correct option is C i,iii,iv are correct

The magnetic moment of $M{n}^{2+}$ is $\sqrt{35}$ because it contains 5 unpaired electrons.
1 Bohr magneton = $9.273\times {10}^{-24}Tesl{a}^{-1}$
Secondary valency of transition metal ion is equal to its coordination number
In a coordination compound, the number of ions or molecules that are coordinated to the central metal ion; its coordination number and $T{i}^{4+}$ is colourless because it contains paired electrons.
