Ti arrow| Ar | 3 d 2 4 s 2 Mn arrow| Ar | 3 d 5 4 s 2 Ni arrow| Ar | 3 d 8 4 s 2 Zn arrow| Ar | 3 d 10 4 s 2 Correct order of I.P. is [ Ti < Mn < Ni < Zn ]

Q. The correct order of the first ionization enthalpies is:

Mn < Ti < Zn < Ni

Ti < Mn < Ni < Zn

Zn < Ni < Mn < Ti

Ti < Mn < Zn < Ni

$T i \to ∣ A r ∣3 d^{2} 4 s^{2}$
$M n \to ∣ A r ∣3 d^{5} 4 s^{2}$
$N i \to ∣ A r ∣3 d^{8} 4 s^{2}$
$Z n \to ∣ A r ∣3 d^{10} 4 s^{2}$
Correct order of I.P. is
$[T i < M n < N i < Z n]$
