Given below are two statements :
Statement $\mathrm{I}:$ Both $\mathrm{CaCl}_{2} \cdot 6 \mathrm{H}_{2} \mathrm{O}$ and $\mathrm{MgCl}_{2} \cdot 8 \mathrm{H}_{2} \mathrm{O}$
undergo dehydration on heating.
Statement II : $\mathrm{BeO}$ is amphoteric whereas the
oxides of other elements in the same group are acidic
In the light of the above statements, choose the correct answer from the options given below :
Correct Option: , 2
(a) $\mathrm{CaCl}_{2} .6 \mathrm{H}_{2} \mathrm{O} \stackrel{\Delta}{\longrightarrow} \underset{\text { (Anhydrous) }}{\mathrm{CaCl}_{2}}+6 \mathrm{H}_{2} \mathrm{O}$
(b) $\mathrm{MgCl}_{2} \cdot 8 \mathrm{H}_{2} \mathrm{O} \stackrel{\Delta}{\longrightarrow} \mathrm{MgO}+2 \mathrm{HCl}+6 \mathrm{H}_{2} \mathrm{O}$
The dehydration of hydrated chloride of calcium can be achieved. The corresponding hydrated chloride of magnesium on heating suffer hydrolysis.
(c) $\mathrm{BeO} \rightarrow$ Amphoteric
$\left.\begin{array}{l}\mathrm{MgO} \\ \mathrm{CaO} \\ \mathrm{SrO} \\ \mathrm{BaO}\end{array}\right] \Rightarrow$ All are basic oxide
