Which of the following is/are true regarding electronegativity.

Answer:

A, B, C, D

Solution:

All options are true.

A. F, O, N, and sp carbon are highly electronegative, enabling H-bonding.

B. Pauling electronegativity values are generally higher than Mulliken values.

C. Hannay-Smith equation estimates ionic character. For HCl, $Δ EN \approx 0.96$ , giving $\approx 17.23%$ ionic character.

D. Lattice energy is released (negative) when ionic compounds form from gaseous ions.
