I think thier speed may differ relatively due the movement of wind on each sides. itz very obvious that they change even the time of the day may count
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.
