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

A

`Ti gt V gt Cr gt Mn`

B

`Cr gt Mn gt V gt Ti`

C

`V gt Mn gt Cr gt Ti`

D

`Mn gt Cr gt Ti gt V`

Text Solution

Verified by Experts

The correct Answer is:
B
Ionisation energy from left to right in a period increases. In all the ions the `2^(nd)` electro are being eliminated from 4s orbital
