JEE Main levelOne or more correct optionsDifficulty 2 of 3pt192
Which of the following statements about Pauling electronegativity is/are correct? (Values: F 3.98, Li 0.98, Be 1.57, Na 0.93, Mg 1.31, Cl 3.16, Br 2.96, I 2.66)
AFluorine has the highest electronegativity of all elements on this scale
BElectronegativity decreases in the order Cl > Br > I
CBe is less electronegative than Mg
DNa is more electronegative than Mg
Answer: A, B
Fluorine (3.98) is the highest, and the halogens fall from 3.16 to 2.96 to 2.66 going down. Be (1.57) is higher than Mg (1.31), and Na (0.93) is lower than Mg (1.31), so the last two statements are false.
