Arrange the following bonds in order of increasing ionic character giving reason

N—H, F—H, C—H and O—H


To arrange the molecules in the increasing order of ionic character, we have to look at the electronegativity difference.


The ionic character is greater in the molecules that are having the greatest electronegativity difference because the electron pair shifts toward a more electronegative atom increasing the ionic character.


The electronegativity difference order in the molecules is as follows:


C-H<N-H<O-H< F-H


Thus, the ionic character order will be:


C-H<N-H<O-H< F-H
