Identify the only INCORRECT statement :-

Answer:

Solution:

(A) Correct: For an isolated gaseous anion, adding another electron requires energy due to electron–electron repulsion, so $Δ H_{e g} > 0$ .

(B) Correct: Pauling electronegativity is a relative scale.

(D) Incorrect: $I E_{2} (M g) = 1451 k J m o l^{- 1}$ , while $I E_{2} (A l) = 1817 k J m o l^{- 1}$ , so $I E_{2} (M g) < I E_{2} (A l)$ .

Therefore, the only incorrect statement is D.
