In the case of alkali metals, the covalent character decreases in the order

A

`MFgtMCIgtMBrgtMI`

B

`MFgtMCIgtMIgtMBr`

C

`MIgtMBrgtMCIgtMF`

D

`MCIgtMIgtMBrgtMF`

Text Solution

Verified by Experts

The correct Answer is:
C
As the size of halide ion decreases, `I^(Θ) gt Br^(Θ) gt CI^(Θ) gt F^(Θ)`, tendency to get polarised by cation `M^(o+)` decreases and hence convalent character decreases.
