A) \[BeC{{l}_{2}}<CaC{{l}_{2}}<MgC{{l}_{2}}<BaC{{l}_{2}}\]
B) \[BeC{{l}_{2}}<MgC{{l}_{2}}<CaC{{l}_{2}}<BaC{{l}_{2}}\]
C) \[BeC{{l}_{2}}<BaC{{l}_{2}}<MgC{{l}_{2}}<CaC{{l}_{2}}\]
D) \[BaC{{l}_{2}}<CaC{{l}_{2}}<MgC{{l}_{2}}<BeC{{l}_{2}}\]
Correct Answer: B
Solution :
Key Idea: The ionic character of halide increases down the group due to decrease in ionisation energy. \[\therefore \] The correct order of increasing ionic character is \[BeC{{l}_{2}}<MgC{{l}_{2}}<CaC{{l}_{2}}<BaC{{l}_{2}}\]You need to login to perform this action.
