Which one of the following is an oxide?

Options

  1. AS i O 2
  2. BK O 2
  3. CB a O 2
  4. DC s O 2

Correct answer

A. S i O 2

Step-by-step solution

S i O 2    is a 3D polymer of tetrahedral S i O 4 - 4 units. S i 4 + +   O 2 − → o x i d e              K + + O 2 − →     sup e r o x i d e     B a 2 + + O 2 2 − → p e r o x i d e     C s + + O 2 − →   sup e r o x i d e
