Question

If two atoms form a mostly covalent bond, what is the range of differences between their electronegativities?

Answer 1

0.5 to 0.9

Step-by-step explanation:

Covalent bonds have an electronegativity range between 0.0 and 1.7

0.0 to 0.4 is a pure covalent bond

0.4 to 0.9 is a slightly polar covalent bond/mostly covalent bond

0.9 to 1.3 is a moderately polar covalent bond

1.3 to 1.7 is a high polar covalent bond

Hope this helps!
