What is the correct order of electronegativity?

What is the correct order of electronegativity?
  1. \(M^{1-} < M^{2-} < M^{3-} < M^{4-}\)
  2. \(M^{1-} > M^{2-} > M^{3-} > M^{4-}\)
  3. \(M^{1-} < M^{2-} < M^{3-} < M^{4-}\)
  4. \(M^{4-} < M^{2-} < M^{3-} < M^{1-}\)

Solution

Higher the positive charge the greater is the EN and higher the negative charge the lesser is the EN. So, EN order is $\mathrm{M}^{-}>\mathrm{M}^{2-}>\mathrm{M}^{3-}>\mathrm{M}^{-4}$ ,
