Explainwhy theelectron gain enthalpy of thefluorineis lessnegativethan that of chlorine |
| Answer» Solution :In F, thenewelectronto beaddedgoes to2p- subshellwhile in C1,it goesto 3p-subshell. Since 2P- subshellin muchsmallerthat 3p-subshellthereforethe addedelectronin F experiences muchstronger REPULSIONS from otherelectronin COMPARISION tothat in C1inotherwordsF does not accepttheincoming electron a electronwith that ease withwhich C1accepts . consequently the electrongainenthalpyof F isless negative THANTHAT of C1 | |
