Question

Which pair of atoms has the highest electronegativity difference?

A. H – S
B. H – Cl
C. N – H
D. O – H
E. C – H

Answer 1

D. O – H

Step-by-step explanation:

Answer 2

D. O – H

Step-by-step explanation:

• The electronegativity of the elements in the question is:

H (2.20), S (2.58), Cl (3.16), N (3.04), O (3.44), and C (2.55).

• Since, the H atom has the lowest electronegativity (2.20) and O atom has the highest electronegativity (3.44).

• So, O - H pair of atoms has the highest electronegativity difference.
