Please drag and drop the selected option in the right place or type it instead
SiO2
CCl4
Si3N4
IBr5
S2F2

Correct Answer

(1) CCl4
(2) SiO2
(3) Si3N4
(4) S2F2
(5) IBr5

Explanation

  1. The name carbon tetrachloride implies one carbon atom and four chlorine atoms, so the formula is CCl4.
  2. The name silicon dioxide implies one silicon atom and two oxygen atoms, so the formula is SiO2.
  3. We have a name that has numerical prefixes on both elements. Trimeans three, and tetra- means four, so the formula of this compound is
    Si3N4.
  4. S2F2
  5. IBr5
