Which of the following orders are correct regarding their covalent character?
i. \(\mathrm{KF} \lt \mathrm{KI}\)
ii. \(\mathrm{LiF} \lt \mathrm{KF}\)
iii. \(\mathrm{SnCl}_2 \lt \mathrm{SnCl}_4\)
iv. \(\mathrm{NaCl} \lt \mathrm{CuCl}\)
The correct option is
- A i, ii, iii only
- B ii, iii, iv only
- C i, iii, iv only
- D i, ii, iv only
Answer & Solution
Correct Answer
(C) i, iii, iv only
Step-by-step Solution
Detailed explanation
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 \(\mathrm{F}^{-}\)so, \(\mathrm{KI}\gt\mathrm{KF}\) (ii)…
