NEET Chemistry Ionic Bond MCQ Question
Which of the following combinations about ionic bonds is correct?
Ionic bonds form between elements with low ionization enthalpy and high electron gain enthalpy; they are typically exothermic.
Ionic bonds are formed exclusively between non-metallic elements; they always have high melting points.
Ionic bonds are always formed as a result of electron sharing between atoms; they are characterized by molecular orbital formations.
Ionic bonds can be formed from cations derived from non-metals and anions from metals; they exhibit low lattice energy.
Correct Answer
Detailed Explanation
Ionic bonds form more easily between elements with low ionization enthalpies and high negative values of electron gain enthalpy, as stated in the NCERT context. Additionally, the process is typically exothermic.
