Answer:
D. O – H
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.
