Explanation:
Detailed explanation-1: -(iv) Polar covalent bond will be formed in the compound between F and J.
Detailed explanation-2: -In the silicon-fluorine bond, the electronegativity difference is 2.2 which would indicate an ionic bond, but since the average electronegativity between silicon and fluorine is (1.8+4.0)/2 or 2.9, which is on the high side, the threshold for electronegativity difference to form an ionic bond is higher.
