Arrange the following in order of the increasing covalent character: `MCI, MBr, MF, MI` (where M = alkali metals) |
|
Answer» `{:(,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. |
