1. ⇒  (MHT CET 2023 11th May Morning Shift )

Which metal halide from following has lowest ionic character ( M = metal atom)?

A. MF

B. MCl

C. MBr

D. MI

Correct Option is (D)

Ionic character of metal halides decreases in the order MF > MCl > MBr > MI , where, M is a monovalent metal. Smaller the size of anion, greater is the ionic character (Fajan's rule). Therefore, MI has the lowest ionic character.

2. ⇒  (MHT CET 2023 11th May Morning Shift )

Which among the following halogens combines readily with metals to form metal halides with highest ionic character?

A. Chlorine

B. Bromine

C. Iodine

D. Fluorine

Correct Option is (D)

Ionic character of metal halides decreases in the order MF > MCl > MBr > MI , where, M is a monovalent metal. Smaller the size of anion, greater is the ionic character (Fajan's rule). Therefore, fluorine forms metal halides with highest ionic character.
