Question

Predict the relative basicity of the following ions F, Cl, Br, I

Solution

Correct option is

F > Cl > Br > I

 

Volume available for the charge in increasing from left to right. So charge density is decreasing from left to right. That is why, basicity of the ions decreases from left to right.   

F > Cl > Br > I.
