Group VI A elements forms oxyacids such as $H_{2} S O 4, H_{2} S e O_{4}, H_{6} T e O_{6}$ .
In the lighter members, $O (2 p) \to X (3 d, 4 d) π$ bonding is significant, strong $π - b o n d s$ are formed to give $X O_{4}^{2 -}$ .
Hence, statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.

Group VI A elements forms oxyacids such as H2SO4,H2SeO4,H6TeO6.In the lighter members, O(2p)→X(3d,4d)π bonding is significant, strong π−bonds are formed to give XO2−4. Hence, statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
