Benzene is considered to be unsaturated because it has double carbon-carbon covalent bonds. These bonds are not restricted to specific carbons, but are de-localized due to the resonance caused by the circular structure of the molecule.

An experimental determination of the molecular mass reveals that a molecule of benzene contains six carbon atoms and six hydrogen atoms, so the molecular formula for benzene is C6H6 (Figure 5). If we know a compound's formula, we can easily determine the empirical formula.

Hydrogen peroxide is manufactured using the anthraquinone process. This process is a cyclic operation where the alkyl anthraquinone is reused. The Synthesis Loop consists of sequential hydrogenation, filtration, oxidation and extraction stages (Figure 1). A number of ancillary processes are also involved.

It needs two more electrons to complete its octet.It therefore, acts as a Lewis acid catalyst in Friedel-Crafts alkylation and acylation reactions of benzene and other aromotic compounds.In these reactions, it helps to generate the electrophile (R+ or RCO+) which attacks the benzene / aromatic ring.

Honeycombs are made from beeswax, a substance created by worker bees. ... Then they chew the wax with a bit of honey and pollen to produce the beeswax. The hexagonal cells serve as storage vessels for honey, as well as homes to raise young bees.

hno3 is added during iodination of benzene. Iodination of benzene is done in presence of acidic oxidising agent such as nitric acid. HNO3 is a strong oxidising agent and hence it will help in the removal of electron from I2 to convert into I+ . HNO will get consumed in the reaction .
