Question

Which bond pair does not have a polar covalent bond?
A. P – Cl
B. B. O – H
C. S – Cl
D. H – Cl
E. E. Cl - Cl

Answer 1

"Cl - Cl" is the bond pair among the choices given in the question that does not have a polar covalent bond. The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer that has actually come to your great help.

Answer 2

Answer:

Cl-Cl

Explanation:

The electronegativity difference would tell us if we have a polar or a non-polar bond. If we have an electronegativity difference below that 0.4 we will have a non-polar bond if we have an electronegativity difference above that 0.4 and below 1.9 we will have a polar bond.

The electronegativity values for all atoms are:

P= 2.1

Cl= 3

O= 3.5

H= 2.1

S= 2.5

When we do the electronegativity difference we will have:

P-Cl = 0.9 => Polar

O-H= 1.4 => Polar

S-Cl= 0.5 => Polar

H-Cl= 0.9 => Polar

Cl-Cl= 0 => Non-Polar
