NEET Chemistry Ionic Bond MCQ Question
Which of the following statements about ionic bonds and lattice enthalpy are correct?
Ionic bonds are formed when atoms achieve octet configuration and lattice enthalpy is the energy required to separate ionic compounds into gaseous ions.
Lattice enthalpy is always negative and indicates the stability of ionic bonds.
The formation of ionic bonds does not depend on the size of the ions involved.
Ionic bonds can be broken easily with a small amount of energy due to their weak nature.
Correct Answer
Detailed Explanation
Statement A is correct as it accurately reflects the formation of ionic bonds and the definition of lattice enthalpy. Statement B is incorrect since lattice enthalpy is positive when separating ions. Statement C is misleading as the size of ions significantly affects lattice enthalpy. Statement D is incorrect because ionic bonds are typically strong and require substantial energy to break.
