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

E.  Cl – Cl

Explanation:

First let's look at the electronegativity values of each of these elements:

P - 2.1

Cl - 3.0

O - 3.5

H - 2.1

S - 1.8

If the electronegativity difference is between 0.4 and 1.9, it's a polar covalent bond. So whichever one isn't between .4 and 1.9, is the answer.

The differences can't be negative.

A.  P – Cl   (3.0 – 2.1) = 0.9   ❌

B.  O – H   (3.5 – 2.1) = 1.4    ❌

C.  S – Cl   (3.0 – 1.8) = 1.2    ❌

D.  H – Cl   (3.0 – 2.1) = 1.2   ❌

E.  Cl – Cl  (3.0 – 3.0) = 0     ✔

the answer is minerals.
