The correct order of decreasing second ...

The correct order of decreasing second ionisation enthalpy of Ti (22), V(23), cr(24) and Mn (25) is

A

`MngtCrgtTigtV`

B

`TigtVgtCrgtMn`

C

`CrgtMngtVgtTi`

D

`VgtMngtCrgtTi`

Text Solution

Verified by Experts

The correct Answer is:
C
`Ti: [Ar]^(18) 3d^(2)4s^(2) , V: [Ar]^(18) 3d^(3)4s^(2)`
`Cr:[Ar]^(18)3d^(5)4s^(1), Mn:[Ar]^(18) 3d^(5)4s^(2)`
Since ionization enthlpy increases across a period, the correct order should be
`MngtCrgtVgtTi`
But Cr with more symmetrical electronic configuration has higher second ionization enthlpy than Mn. hence the correct order is `CrgtMngtVgtTi`.
