\(\mathrm{BeF}_{2}\) is soluble in water, whereas, the fluorides of other alkaline earth metals are insoluble because of
1 Ionic nature of \(\mathrm{BeF}_{2}\)
2 Greater hydration energy of \({\rm{B}}{{\rm{e}}^{{\rm{2 + }}}}\) ion
3 Covalent nature of \(\mathrm{BeF}_{2}\)
4 None of the above

Some of the Group 2 metal halides are covalent and soluble in organic solvents. Among the following metal halides, the one which is soluble in ethanol is
1 \(\mathrm{BeCl}_{2}\)
2 \(\mathrm{CaCl}_{2}\)
3 \(\mathrm{MgCl}_{2}\)
4 \(\mathrm{SrCl}_{2}\)

Which of the alkaline earth metal halides given below is essentially covalent in nature?
1 \(\mathrm{SrCl}_{2}\)
2 \(\mathrm{MgCl}_{2}\)
3 \(\mathrm{BaCl}_{2}\)
4 \(\mathrm{CaCl}_{2}\)
Explanation:
Covalent character increases, when the cation has small size and high charge density. Among all these, \({\rm{M}}{{\rm{g}}^{{\rm{2( + )}}}}\) size is smaller so \(\mathrm{MgCl}_{2}\) tends to be more covalent in nature.

The structures of beryllium chloride in solid state and vapour phase, are :
1 Linear in both
2 Dimer and Linear, respectively
3 Chain in both
4 Chain and dimer, respectively
Explanation:
\(\mathrm{BeCl}_{2}(\mathrm{~g})\) - Vapour phase exist as dimer \(\mathrm{BeCl}_{2}(\mathrm{~s})\) - Solid phase exist as chain polymer
As the size of the anion increases, the covalent character increases and hence the m.p. decrease.
