Answer:
Ionic
character in a covalent bond is observed when there is sufficient difference in
the electro negativity of the two atoms.
Ionic
character \[\propto \] Electro negativity difference
Order
of increasing ionic character
\[\underset{\underbrace{2.5\,\,\,\,\,\,\,\,\,2.1}_{0.4}}{\mathop{C-H}}\,<\underset{\underbrace{3.0\,\,\,\,\,\,\,\,\,\,\,\,\,\,2.1}_{0.9}}{\mathop{N-H}}\,<\underset{\underbrace{3.5\,\,\,\,\,\,\,\,\,2.1}_{1.4}}{\mathop{O-H}}\,<\underset{\underbrace{4.0\,\,\,\,\,\,\,2.1}_{1.9}}{\mathop{F-H}}\,\]
