#1

Arrange the following bonds in order of increasing ionic character giving reason.
N—H, F—H, C—H and 0—H


#2

Greater is the electronegativity difference between the two bonded atoms, greater in the ionic character.

Therefore, increasing order of ionic character of the given bonds is as follows
C—H < N—H < O—H < F—H
