The correct order of decreasing second ionisation enthalpy of \( \mathrm{Ti}(22), \mathrm{V}(23), \mathrm{Cr}(24) \) and \( \operatorname{Mn}(25) \) is :
(W)
(1) \( \mathrm{Mn}\mathrm{Cr}\mathrm{Ti}\mathrm{V} \)
- (2) \( \mathrm{Ti}\mathrm{V}\mathrm{Cr}\mathrm{Mn} \)
(3) \( \mathrm{Cr}\mathrm{Mn}\mathrm{V}\mathrm{Ti} \)
(4) \( \mathrm{V}\mathrm{Mn}\mathrm{Cr}\mathrm{Ti} \)
