The correct Answer is:
To solve the question "The power of an atom to attract the shared pair in a molecule," we need to analyze the options provided: electron gain enthalpy, electronegativity, ionization enthalpy, and none of these. ### Step-by-Step Solution: 1. **Understand the Terms**: - **Electron Gain Enthalpy**: This refers to the energy change when an atom gains an electron to form an anion. It does not describe the attraction of shared electrons in a bond. - **Ionization Enthalpy**: This is the energy required to remove an electron from an atom. This also does not relate to the attraction of shared electrons in a molecule. - **Electronegativity**: This is the measure of the tendency of an atom to attract a bonding pair of electrons (shared pair) towards itself in a chemical bond. 2. **Identify the Correct Concept**: - Since the question specifically asks about the power of an atom to attract shared pairs of electrons in a molecule, we need to focus on electronegativity. Electronegativity is the property that describes how strongly an atom can attract electrons in a covalent bond. 3. **Conclusion**: - Therefore, the correct answer to the question is **electronegativity**. ### Final Answer: - The power of an atom to attract the shared pair in a molecule is **electronegativity**. ---
