Dear sir Pease explain me following questions: 1) what are peroxides? 2) What is superoxide? 3) What is difference b/w peroxide and superoxide? 4)What is binary compound?

1) A peroxide is a compound containing an oxygen–oxygen single bond or the peroxide anion ([O?O]^2–). The O?O group is called the peroxide group or peroxo group.

2) A superoxide, also known by the obsolete name hyperoxide, is a compound that contains the superoxide anion with the chemical formula O₂^?.

3) A binary compound is a chemical compound that contains exactly two different elements in different proportions. Examples of binary ionic compounds include calcioum chloride (CaCl₂), sodium fluoride (NaF), and magnesium oxide (MgO), while examples of binary covalent compounds include water (H₂O), carbon monoxide (CO), and sulphur hexafluoride (SF₆).
