Arrange the following in order of the increasing covalent character:
`MCl, MBr, MF, MI` (where M = alkali metals)

Text Solution

Verified by Experts

`{:(,MFlt,MCllt,MBrlt,MI),("Size of anion",F^(Θ)lt,Cl^(Θ)lt,Br^(Θ)lt,I^(Θ)),("Degree of polarisation",F^(Θ)lt,Cl^(Θ)lt,Br^(Θ)lt,I^(Θ)),("Covalent character",MFlt,MCllt,MBrlt,MI):}`
With increasing size of the anion, degree of polarisation by the cation increses and hence the covalent character increases.
