Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
In addition to hydrogen peroxide, some other major classes of peroxides are: Peroxy acids, the peroxy derivatives of many familiar acids, examples being peroxymonosulfuric acid and peracetic acid, and their salts, one example of which is potassium peroxydisulfate. Main group peroxides, compounds with the linkage E−O−O−E (E = main group ...
Dialkyl peroxides, e.g., dicumyl peroxide, are synthesized by addition of hydrogen peroxide to alkenes or by O-alkylation of hydroperoxides. Diacyl peroxides are typically prepared by treating hydrogen peroxide with acid chlorides or acid anhydrides in the presence of base: [1] H 2 O 2 + 2 RCOCl → (RCO 2) 2 + 2 HCl H 2 O 2 + (RCO) 2 O → ...
Tie up loose ends. Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom. The second oxygen atom in each structure will be single-bonded to the nitrogen atom. Place brackets around each structure, and add the charge (−) to the upper right outside the brackets.
The structure of dioxygen difluoride resembles that of hydrogen peroxide, H 2 O 2, in its large dihedral angle, which approaches 90° and C 2 symmetry. This geometry conforms with the predictions of VSEPR theory. Dioxygen difluoride's structure

The molecule has a bent structure. [3] The superoxide anion, • O − 2, and the hydroperoxyl radical exist in equilibrium in aqueous solution: • O − 2 + H 2 O ⇌ HO • 2 + HO −. The pK a of HO 2 is 4.88. Therefore, about 0.3% of any superoxide present in the cytosol of a typical cell is in the protonated form. [4] It oxidizes nitric ...
The structure of hydrogen disulfide is similar to that of hydrogen peroxide, with C 2 point group symmetry. Both molecules are distinctly nonplanar. The dihedral angle between the H a −S−S and S−S−H b planes is 90.6°, compared with 111.5° in H 2 O 2. The H−S−S bond angle is 92°, close to 90° for unhybridized divalent sulfur. [1]
