MCQ
What is the correct order of acidic nature
  • A
    $SO_2 < SeO_2 < TeO_2$
  • $SO_2 > SeO_2 > TeO_2$
  • C
    $SO_2 = SeO_2 = TeO_2$
  • D
    $SO_2 < SeO_2 > TeO_2$

Answer

Correct option: B.
$SO_2 > SeO_2 > TeO_2$
b
Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table
