The correct increasing order of polarising power is

Which compound has the highest covalent character?

The percentage of covalent character in an ionic bond is determined by which of the following?

Which of the following statements are correct?
$(A)$ Both $LiCl$ and $MgCl_2$ are soluble in ethanol.
$(B)$ The oxides $Li_2O$ and $MgO$ combine with excess of oxygen to give superoxide.
$(C)$ $LiF$ is less soluble in water than other alkali metal fluorides.
$(D)$ $Li_2O$ is more soluble in water than other alkali metal oxides.
Choose the most appropriate answer from the options given below.

The correct order of covalent bond character of $BCl_3, CCl_4, BeCl_2, LiCl$ is

Given below are two statements:
Statement $I$: The correct order in terms of bond dissociation enthalpy is $Cl_{2} > Br_{2} > F_{2} > I_{2}$.
Statement $II$: The correct trend in the covalent character of the metal halides is $[SnCl_{4} > SnCl_{2}]$,$[PbCl_{4} > PbCl_{2}]$ and $[UF_{4} > UF_{6}]$.
In the light of the above statements,choose the correct answer from the options given below:
