Identify metal halide from following having highest ionic character? (M= metal atom )

Options

  1. AMF
  2. BMBr
  3. CMI
  4. DMCl

Correct answer

A. MF

Step-by-step solution

According to fajan's rule as the size of anion increases its ionic character will decrease. Since the size of F ⁻ is the lowest among halides hence MF has the highest ionic character. Order of ionic character: MF > MCl > MBr > MI
