Question

Rank the bonds from highest polarity to lowest polarity. (Highest on top)

Answer 1

Answer:

O-H

N-H

Br-H

C-H

Si-H

Explanation:

Oxygen having electronegativity of 3.44 eV while hydrogen having electronegativity 22.2 eV. So oxygen will attract electrons more strongly than hydrogen because of higher electronegativity and produce a dipole.  the electronegativity difference between them is  1.24eV which means it is polar compounds because if the electronegativity difference between bonded molecules are  0.4-2.0 eV indicated the compounds is polar. And same rule apply for rest of the options.
