Design a synthesis of 2-bromo-1-chloro-4-nitrobenzene from benzene or any mono-substituted benzene. Part 1 out of 6 choose the b
Oxana [17]

2-bromo-1-chloro-4-nitrobenzene  is being synthesized in following sequence:

Step 1: Chlorination of Benzene:

                                                     This is Halogenation reaction of benzene. In this step benzene is reacted with Chlorine gas in the presence of lewis acid (i.e. FeCl₃). This results in the formation of Chlorobenzene as shown in red step below.

Step 2: Nitration of Chlorobenzene:

                                                          The chlorine atom on benzene has a ortho para directing effect. Therefore, the nitration of chlorobenzene will yield para nitro chlorobenzene as shown in blue step below.

Step 3: Bromination of 1-chloro-4-nitrobenzene:

                                                                               In this step bromination is done by reacting bromine in the presence of lewis acid. The chlorine being ortho para directing in nature and nitro group being meta directing in nature will direct the incoming Br⁺ (electrophile) to the desired location. Hence, 2-bromo-1-chloro-4-nitrobenzene is synthesized in good yield.

What is a chemical formula?
krek1111 [17]

Answer:

A. An identification of the atoms in a molecule

Explanation:

The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.

Therefore, a chemical formula allows us to identify atoms that are within a molecule.

A molecule is a covalent compound that has discrete or separate units.

For example;

         HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.

Express your answer as a balanced chemical equation. Identify all of the phases in your answer.
SpyIntel [72]

Answer:

H₂S(aq)+ 2 LiOH(aq) → Li₂S(aq) + 2 H₂O(l)

6 HI(aq) + 2 Al(s) → 2 AlI₃(aq) + 3 H₂(g)

2 H₂SO₄(aq) + TiO₂(s) → Ti(SO₄)₂(aq) + 2 H₂O(l)

H₂CO₃(aq) + 2 LiOH(aq) → Li₂CO₃(aq) + 2 H₂O(l)

Explanation:

H₂S(aq)+ 2 LiOH(aq) → Li₂S(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.

6 HI(aq) + 2 Al(s) → 2 AlI₃(aq) + 3 H₂(g)

This is a single displacement reaction.

2 H₂SO₄(aq) + TiO₂(s) → Ti(SO₄)₂(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.

H₂CO₃(aq) + 2 LiOH(aq) → Li₂CO₃(aq) + 2 H₂O(l)

This is a neutralization reaction. The products are salt and water.
