In the case of alkali metals, the covalent character decreases in the order: : `MF gt MCl gt MBr gt MI`, `MF gt MCl gt MI gt MBr` , `MI gt MBr gt MCl gt MF`, `MCl gt MI gt MBr gt MF`

`MF gt MCl gt MBr gt MI`

`MF gt MCl gt MI gt MBr`

`MI gt MBr gt MCl gt MF`

`MCl gt MI gt MBr gt MF`

Text Solution

Verified by Experts

The correct Answer is:

As the size of halide ion decreases, `I^(ѳ) gt Br^(ѳ) gt Cl^(ѳ) gt F^(ѳ)`, tendency to get polarised by cation `M^(o+)` decreaes and hence covalent character decreases.
