Arrange the following compounds in order of increasing solubility (i) \(\mathrm{MgF}_{2}\) (ii) \(\mathrm{CaF}_{2}\) (iii) \(\mathrm{BaF}_{2}\)
1 (i) \( < \) (ii) \( < \) (iii)
2 (ii) \( < \) (i) \( < \) (iii)
3 (ii) \( < \) (iii) \( < \) (ii)
4 (iii) \( < \) (ii) \( < \) (i)
Explanation:
Order of stability: \(\mathrm{MgF}_{2}>\mathrm{CaF}_{2}>\mathrm{BaF}_{2}\) Order of solubility: \(\mathrm{MgF}_{2} < \mathrm{CaF}_{2} < \mathrm{BaF}_{2}\)

The correct order of increasing ionic character is
315831
Among the following alkaline earth metal halides one which is covalent and soluble in organic solvents is:
1 Strontium chloride
2 Magnesium chloride
3 Beryllium chloride
4 Calcium chloride
Explanation:
So \(\mathrm{BeCl}_{2}\) has high covalent nature so it is soluble in organic solvent.

Consider the following structure: Choose the incorrect statement regarding above structure. I. This stucture is accebtable at vapour phase. II. Above 1200 K it dissociates into linear polymer. III. This structure is acceptable only at very low temperature.
1 I and III
2 I and II
3 All are correct
4 I, II, III
Explanation:
All are incorrect statements. Its correct form as follows: I. The given structure is acceptable at solid phase II. Above \(1200 \mathrm{~K}\), it dissociates to linear monomer III. This structure is acceptable at high temperature also So, the option (4) is correct.
