Which of the following orders are correct regarding their covalent character? i. KF KI ii. LiF KF iii. SnCl ₂ SnCl ₄ iv. NaCl CuCl The correct option is

Options

  1. Ai, ii, iii only
  2. Bii, iii, iv only
  3. Ci, iii, iv only
  4. Di, ii, iv only

Correct answer

C. i, iii, iv only

Step-by-step solution

According to Fajan rule, for covalent character, cation should be small in size and should have high positive charge and anion should be large in size and contain high negative charge. (i) Iodine have more size than F ⁻ so, KI KF (ii) K ⁺ have more size the Li ⁺ so, LiF KF (iii) Sn ²⁺ and Sn ⁴⁺ Sn ⁴⁺ carry more charge than Sn ²⁺ so, SnCl ₄ SnCl ₂ (iv) Cu ⁺ have pseudo configuration so it has more covalent character than NaCl . CuCl NaCl (i), (iii) and (iv) are correct
