Question

Which pair in the following has maximum and minimum ionic character respectively?

• A. $LiCl,RbCl$
• B. $RbCl,Be{Cl}_2$
• C. $Be{Cl}_2,RbCl$
• D. $AgCl,RbCl$

Answer 1

The correct option is B $RbCl,Be{Cl}_2$

Maximum ionic character is shown by largest cation and smallest anion. For minimum ionic character. Smallest cation and largest anion. Here anion is same. So cation of more size shows maximum ionic character. '$Rb$' has largest size and $Be$ has small size. So $RbCl$ has maximum and $BeC{l}_2$ has minimum ionic character.
