Question

Explain any 2 factor that favour the covalent character of ionic bond

Answer 1

Covalent character of ionic bond is caused by polarisation.

The ability to polarise the electron cloud depends on

• The size of cation- smaller cation has more concentrated charge as charge/radius ratio is high. this increases the polarising power.
• The size of anion- Bigger anion is more readily polarised as the electron cloud is large and diffuse.
• Eg, LiCl, NaI
