Question

Given below are two statements:

Statement I: Fluorine has most negative electron gain enthalpy in its group.

Statement II: Oxygen has least negative electron gain enthalpy in its group.

Choose the correct option:

Canvas Classes · Accepted Answer

Strategy:
 Analyze Electron Gain Enthalpy () anomalies in Groups 16 and 17. Small atoms like Oxygen and Fluorine exhibit high electron repulsion in their compact  orbitals.

Step 1: Evaluate Statement I
- In Group 17, Chlorine () is more negative than Fluorine ().
- Fluorine does not have the most negative . (False)

Step 2: Evaluate Statement II
- In Group 16, Oxygen has the least negative  () compared to Sulfur, Selenium, and Tellurium.
- This is due to shielding and inter-electronic repulsion
