Question

Mention factors that influence ionic, covalent,metallic, hydrogen and dative bonding

Answer 1

Answer:

1. Polarizing capacity of cation
2. Polarisability of anion
3. Size of cation
4. Size of anion
5. Presence of hydrogen and a strong electronegative element like F, O, N in the compound

Explanation:

For forming a stable ionic bond, Polarizing capacity of cation and Polarisability of anion must be smaller.

Polarizing capacity of cation is inversely proportional to its size. If size is small it's charge density would be very high and so it's Polarizing capacity.

Polarisability of anion is directly proportional to its size.

So a larger cation and smaller anion form a stable ionic bond. CsF is the most stable ionic compound as Cs is the largest cation and F is the smallest anion.

If the compound has hydrogen and a strong electronegative atom like F, O, N, a hydrogen bond is formed between hydrogen and the strong electronegative atom.

Metallic bond is formed between the atoms present in metals.
