    S block has less covalent character than d block elements overall order HgCl2>cdcl2>zncl2 for d block for s block cacl2>srcl2>bacl2 Explanation:- we can apply fajan’s rule.. Which states “cation with smaller size and greater charge and anion with larger size and less charge has more polarizing power” So a more covalent compound is formed with smaller cation and larger anion. so order becomes hgcl2>cdcl2>zncl2> cacl2>srcl2>bacl2
