Question

For electron gain enthalpies of the elements denoted as $\Delta_{ eg } H$, the incorrect option is :

• A. $\Delta_{ eg } H ( Cl )<\Delta_{ eg } H ( F )$
• B. $\Delta_{ eg } H ( I )<\Delta_{ eg } H ( At )$
• C. $\Delta_{ eg } H ( Te )<\Delta_{ eg } H ( Po )$
• D. $\Delta_{ eg } H ( Se )<\Delta_{ eg } H ( S )$

Answer 1

Answer: (D)

$\Delta_{ eg } H ( Se )<\Delta_{ eg } H ( S )$

Answer 2

Correct answer is (a) Δeg​H(Cl)<Δeg​H(F)
