A) -296, -325, -333 and -349
B) -333, -325, -349 and -296
C) -349, -333, -325 and -296
D) -333, -349, -325 and -296
Correct Answer: D
Solution :
[d]| Electron gain enthalpy is most negative for chlorine followed by fluorine and bromine and least negative for iodine among given elements. |
| So, \[F(\,333\text{ }kJ\text{ }mo{{l}^{1}})\] |
| \[Cl\,(\,349\text{ }kJ\text{ }mo{{l}^{1}})\] |
| \[Br\,(\,325\text{ }kJ\text{ }mo{{l}^{1}})\] |
| \[I\,(\,296\text{ }kJ\text{ }mo{{l}^{1}})\] |
