How many factors will contribute to major role in covalent character of a compound?

a. Polarising power of cation

b. Polarisability of the anion

c. Distortion caused by cation

d. Polarisability of cation

What is Fajan rule?

What is dipolarisation?

Polarisation power of a cation increases when

Which has more covalent nature ${\mathrm{Na}}_2{\mathrm{SO}}_3$ or ${\mathrm{Na}}_2{\mathrm{SO}}_4$.

Covalent oxide is

The compound with more covalent character in the following is

Choose the correct option from the following

State the Fajan's rule.

Fajans' rule states that a compound with low positive charge, large cation and small anion has covalent bond where as a compound with high positive charge, small cation and large anion are ionic bonded.

Why is covalent character directly proportional to polarising power?

Explain why cation are smaller and anions larger in radii than their parent atoms?

The size of cation is smaller than its parent atom. Why?

Write the electronic configuration of calcium.

${\mathrm{AlCl}}_3$ is an electron deficient compound but ${\mathrm{AlF}}_3$ is not. This is because

Assertion $\left(\mathrm{A}\right):$ Covalent character follows: $\mathrm{NaCl}<{\mathrm{MgCl}}_2<{\mathrm{BeCl}}_2<\mathrm{LiCl}$
Reason $\left(\mathrm{R}\right):$ According to Fajan's rules, covalent character of ionic compounds increases with decrease in size of cation.

Which of the following compounds is polar ?
