A) \[Mn<Ti<Zn<Ni\]
B) \[Ti<Mn<Ni<Zn\]
C) \[Zn<Ni<Mn<Ti\]
D) \[Ti<Mn<Zn<Ni\]
Correct Answer: B
Solution :
\[Ti\to |Ar|3{{d}^{2}}4{{s}^{2}}\] \[Mn\to |Ar|3{{d}^{5}}4{{s}^{2}}\] \[Ni\to |Ar|3{{d}^{8}}4{{s}^{2}}\] \[Zn\to |Ar|3{{d}^{10}}4{{s}^{2}}\] Correct order of I.P. is\[\left[ Ti<Mn<Ni<Zn \right]\]
