Question:

$\text{The basic difference between the electron gain enthalpy (E}_a\text{) and electronegativity (E}_N\text{) is:}$

Options:

1. $\text{E}_a \text{ is the tendency to lose electrons, while E}_N \text{ is the tendency to repel the shared pairs of electrons.}$
2. $\text{E}_a \text{ is the tendency to gain neutrons, while E}_N \text{ is the tendency to attract the shared pairs of electrons.}$
3. $\text{E}_a \text{ is the tendency to donate electrons, while E}_N \text{ is the tendency to attract the shared pairs of molecules.}$
4. $\text{E}_a \text{ is the tendency to gain electrons, while E}_N \text{ is the tendency to attract the shared pairs of electrons.}$ (Correct)

Solution:

$\text{HINT: Electron gain enthalpy is applicable for atoms, whereas electronegativity is applicable to molecules.}$\n\n$\text{Explanation:}$\n\n$\text{Electron gain enthalpy - Tendency to gain electrons for an isolated gaseous atom is its electron gain enthalpy.}$\n\n$\text{Electronegativity - Tendency to attract the shared pairs of electrons for an atom that is in a chemical compound is its electronegativity.}$
