A) \[BeC{{l}_{2}}<MgC{{l}_{2}}<CaC{{l}_{2}}<BaC{{l}_{2}}\]
B) \[BeC{{l}_{2}}<CaC{{l}_{2}}<MgC{{l}_{2}}<BaC{{l}_{2}}\]
C) \[MgC{{l}_{2}}<CaC{{l}_{2}}<BeC{{l}_{2}}<BaC{{l}_{2}}\]
D) \[BaC{{l}_{2}}<CaC{{l}_{2}}<MgC{{l}_{2}}<BeC{{l}_{2}}\]
Correct Answer: A
Solution :
Order of polarising power of \[B{{e}^{2+}}>M{{g}^{2+}}>C{{a}^{2+}}>B{{a}^{2+}}\] Thus, ionic nature is of following order \[BaC{{l}_{2}}<MgC{{l}_{2}}<CaC{{l}_{2}}<BaC{{l}_{2}}\]You need to login to perform this action.
