Which one of the following arrangements represents the correct order of electron gain enthalpy of the given atomic species?A. `OltSltFltCl`B. `ClltFltSltO`C. `SltOltCiltF`D. `FltClltOltS` |
|
Answer» Correct Answer - A Electron gain enthalpy becomes more negative across a period while it becomes less negative in a group However,electron gain enthalpy of O or F is less than that of the succeding element.When electron is added to n=2,the repulsion is more than when it is added to n=3 in case of Cl or S. |
