Question

Arrange the bonds between H, O, and F from most polar to least polar based on electronegativity.

Answer 1

Answer:

H-F> H-O> O-F

while H-H is nonpolar.

Explanation:

The bond is polar when electronegativity difference of both bonded atom is greater than 0.4.

Electronegativity values of O. F and H are

O = 3.4

H = 2.2

F = 3.98

For O-F

3.98 - 3.4 = 0.58

For H-F

3.98 - 2.2 = 1.78

For H-O

3.4 - 2.2 =  1.2

For H-H

2.2 -2.2 = 0

So H-H is nonpolar.
