Question

which pair of atoms had the highest electronegavity difference

Answer 1

To find out the electronegativity of each pair, work it out by listing them.

H = 2.2

S = 2.1

N = 3.0

Cl = 3.0

O = 3.5

C = 2.5

H – S -> 2.2 - 2.1 = 0.1

H – Cl -> 2.2 - 3.0 = -0.8

N – H -> 3.0 - 2.2 = 0.8

O – H -> 3.5 - 2.2 = 1.3

C – H-> 2.5 - 2.2 = 0.3

So, the pairs that has the highest electronegativity is H-Cl and N-H.
