Which of the following electronegativity order is incorrect?

(Memory Based JEE Mains 22/01/2025 ,Shift -1)

a

Mg < Be < B < N

b

Al < Si < C < N

c

S < Cl < O < F

d

Al < Mg < B < N

✓ Correct answer: d)

Al < Mg < B < N

Explanation

The electronegativity values are:

Al ≈ 1.5
Mg ≈ 1.2
B ≈ 2.0
N ≈ 3.0
The order is incorrect because Mg has a lower electronegativity than Al
