Howwould you react to thestatementthat theelectronegativity of N onPaullingscaleis 3.0in allthenitrogen compound ? |
| Answer» Solution :The electronegativityof any GIVEN atom is notconstant . Thereforethe STATEMENT that theelectronegativityof N onPaulingscale is3.0in allnitrogencompounds is worng. Actually electronegativityvarieswiththe stateof hybridizationand theoxidation stateof the ELEMENT. Theelectronegativityincreases as thepercentage of s- character of a hybridorbitalincreasesor theoxidation stateof theelementincreases. Forexamplethe electronegativeof Nincreasesas we movefrom `sp^(3) -sp^(2)-sp-` hybridorbital. SIMILARLY, the electronegativityof N in `NO_(2)` whereoxidationstateof N is+ 4is higherthan that in NOwherethe oxidationstateof N is + 2 | |
