Q17 / 160 · TS EAMCET 2022 (19 Jul Shift 1) · Chemistry

The acidic oxide from the following is

  • A
    $\mathrm{SnO}_2$
  • Correct answer
    B
    $\mathrm{SiO}_2$
  • C
    $\mathrm{PbO}_2$
  • D
    $\mathrm{SnO}$

Solution

On moving down the group, the tendancy to lose electron increases due to which basic character of oxides increases and acidic character decreases. Hence, $\mathrm{SiO}_2$ form acidic oxide.

Hence, the correct answer is option: 'B'.
