Arrange the following bonds in order of increasing ionic character giving reasonN-H,F-H,C-HandO-H

Answer»

Solution :Increasing ionic CHARACTER of the GIVEN bonds is :
Electronegativity difference :`{:(N-H "" lt ""N-H""lt ""O-H ""lt ""F-H),("(2.5-2.1)(3.0-2.1)(3.5- 2.1)(4.0-2.1)"),( = "0 . 4= 0.9= 1.4= 1. 9 "):} `
Greater is the electronegativity differnce BETWEENTHE two bonded atoms, greater is the ionic character.
