Question

Which pair of elements has maximum electronegativity difference? (A) Li F (B) Na F (C) Na Br (D) Na Cl

Tardigrade Admin · Accepted Answer

Among Li Na, Na is more electropositive Among F, Cl Br, F is most electronegative. So, Na F will have maximum electronegativity difference. EN value = beginmatrixF&CI&Br&I&Li&Na 4&3&2.8&2.5&1&0.9 endmatrix

Q. Which pair of elements has maximum electronegativity difference?

Li & F

Na & F

Na & Br

Na & Cl

Among Li & Na, Na is more electropositive
Among F, Cl & Br, F is most electronegative.
So, Na & F will have maximum electronegativity difference.
EN value = $F 4 C I 3 B r 2.8 I 2.5 L i 1 N a 0.9$
