Question

Which of the following have peroxy linkages?
A. ${H_2}Ti{O_4}$
B. $Os{O_4}$
C. ${K_2}C{r_2}{O_7}$
D. $Cr{O_5}$

Answer 1

Hint: Peroxide, any of the chemical compounds in which two oxygen atoms are bound together by a single covalent bond. Several organic and inorganic peroxides are sometimes useful as bleaching agents, initiators of polymerization reactions, and also in the preparation of hydrogen peroxide (q.v.) and other oxygen compounds.

Step-By-Step answer:
Negatively charged peroxide ion $\left( {{O_2}^{2 - }} \right)$ is found in inorganic compounds and can be known as salts of very mild hydrogen peroxide acid; sources are sodium peroxide $\left( {N{a_2}{O_2}} \right)$, a bleaching agent, and barium peroxide $\left( {Ba{O_2}} \right)$, previously used as a source of hydrogen peroxide.
A peroxy linkage is defined as $\left( { - O - O - } \right)$ bond.
This type of linkage is present in ${H_2}Ti{O_4}$. It has one peroxy linkage and the other compound is $Cr{O_5}$ which has two peroxy linkages.
In two categories there are peroxides which are covalently connected to atoms other than hydrogen, one or two of the oxygen atoms. The inorganic compound Cumene Hydroperoxide, used as the polymerisation initiator, the cause of phenol, acetone and peroxydisulfuric acid, used as an oxidizing material, is one group. Di-tert-butyl peroxide and ammonium peroxydisulfate are both of the other category and are the inductors.
Hydrogen peroxide ${H_2}{O_2}$, commonly referred to as "peroxide," is the most common peroxide. This is marketed in varying amounts as a solution in water.

Note: Since the peroxide of hydrogen is almost colourless, these solutions are likewise. It is used primarily as an oxidant and bleaching agent. Nonetheless, hydrogen peroxide, primarily due to a variety of oxidase enzymes, is also biochemically produced in the human body. Once in contact with organic compounds, condensed solutions are likely to be harmful.
