Nitrobenzene contains 5 hydrogen atoms, 6 carbon atoms, 2 oxygen atoms, and 1 nitrogen atom. what is the chemical formula for ni
ollegr [7]

C₆H₅NO₂

<h3>Further explanation</h3>

Nitrobenzene contains:

  • 5 hydrogen atoms,
  • 6 carbon atoms,
  • 2 oxygen atoms, and
  • 1 nitrogen atom.

The chemical formula for nitrobenzene is C₆H₅NO₂.

Nitrobenzene is one of benzene derivatives, precisely including the type of monosubstituted benzenes.

The molecular structure of phenyl  \boxed{ \ C_6H_5- \ } is formed by removing one H atom from the benzene \boxed{ \ C_6H_6 \ } molecule. A substituent is bound to the C atom which loses the H atom so it is called monosubstituted benzene.

In the naming of monosubstituted benzenes, benzene is the parent name and the substituent is indicated by a prefix.

  • nitro is the substituent
  • benzene is the parent name

When benzene is reacted with a mixture of concentrated nitric acid and concentrated sulfuric acid, it yields nitrobenzene.

\boxed{ \ C_6H_6 + HNO_2 \ (with \ H_2SO_4 \ in \ 30^0C-40^0C) \rightarrow C_6H_5NO_2 + H_2O}

<u>Notes:</u>

  • Benzene and compounds having similar chemical properties to benzene are called aromatic compounds.
  • Benzene is a colorless, poisonous liquid with a specific odor. it dissolves in organic solvents in organic solvents such as alcohol, ether, and acetic acid. Benzene is also good for non-polar substances.
  • Nitrobenzene is used in the manufacture of aniline and other organic chemicals. Nitrobenzene is a pale yellow, oily, and highly toxic liquid with the odor of bitter almonds.
