An ionic bond is the electrostatic attraction between positive and negative ions which are formed by two different elements when

A

both have low negative electron gain enthalpy

B

both have high ionization enthalpy

C

one of the elements has low ionization enthalpy and the other has a high negative electron gain enthalpy

D

one of the elements has high `Delta_1H` and the other has a low negative `Delta_(eg)H`

Text Solution

Verified by Experts

The correct Answer is:
C
Because the formation of ionic bonds and, hence, the formation of ionic compounds primarily depends upon the ease of formation of the positive ions (favored by low `Delta_iH`) and negative ions (favored by high negative `Delta_(eg)H`) from neutral atoms.

  • Ionic bond is defined as the electrostatic force of attraction holding the oppositely charged ions. Ionic compounds are mostly crystalline solid having high melting and boiling points, electrical conductivity in moleten state, solubility in water etc. Covalent bond is defined as the force which binds atoms of same or different elements by mutual sharing of electrons in a covalent bond. Covalent compounds are solids, liquids or gases. They have low melting and boiling points compounds. They are more soluble in non-polar solvents. The amount of energy released when one mole of ionic solid is formed by packing of gaseous ion is called :

    A
    Ionisation energy
    B
    Solvation energy
    C
    Lattice energy
    D
    Hydration energy
