Vedclass · Answer

(B) The assertion is correct because $BeCl_2$ is covalent due to the high polarizing power of the small $Be^{2+}$ ion (Fajans' rule),while $MgCl_2$ and $CaCl_2$ are ionic.The reason is also correct because $Be$ is indeed the first member of group $2$.However,the reason is not the correct explanation of the assertion. The covalent nature of $BeCl_2$ is due to the small size and high charge density of the $Be^{2+}$ ion,not simply because it is the first member of the group.

Assertion : Of the various chlorides of alkaline earth metals $BeCl_2$ is covalent in nature,whereas $MgCl_2$ and $CaCl_2$ are ionic compounds.
Reason : $Be$ is the first member of group $2$.
