Question

In each reaction box place the best reagent and conditions from the list below benzene 3 boxes

Answer 1

The best reagent and conditions from the list below benzene 3 boxes are as attached in the picture below

Explanation:

In each reaction box place the best reagent and conditions from the list below benzene 3 boxes.

A reagent is a substance or compound added to a system causing a chemical reaction. Whereas Benzene is an organic chemical compound with the chemical formula C6H6.

Br2 (Diatomic Bromine) , FeBrg AICI: CI . AICI Br2 CH3CH2CH2CI, AICI HNO3, H2SO4 NBS, ROOR, hv NaBH4 AICI H2 Zn(Hg), HCI CH3CH2CI, AICI

• Aluminum chloride is a chemical compound with the chemical formula AlCl3. It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of the chemical industry.
• BM2 presents a unique opportunity to understand how different chemical systems perform similar functions.
• Zinc amalgam (Zn-Hg) has one important use: in the Clemmensen reduction of ketones to alkanes. The definition of an amalgam is a mixture of metals and mercury, that can be man-made or can be naturally occurring. The example of an amalgam is a mixture of silver and mercury which is used as a dental filling.
• Hydrochloric acid is the aqueous solution of hydrogen chloride. It is a strong mineral acid with many industrial uses.

Answer 2

Answer : The correct answer is 1) AlCl₃ - CH₃Cl 2) HNO₃ -H₂SO₄ at room temperature 3) Fuming HNO₃ -H₂SO₄ at 90-100 ⁰ C heat .

I think this reaction is forming 2,4,6- trinitrotoluene from benzene, since the product is not mentioned. Following are the steps to convert Benzene to 2,4,6 trinitrotoluene .

Step 1: Conversion of Benzene to Toluene .

Benzene can be converted to toluene by Friedel Craft Alkylation of benzene . In this reaction reagent AlCl₃ and Ch3Cl is used . Electrophile CH³⁺ is produced which attached on carbon of benzene and formation of Toluene and HCl occur.

$Benzene \frac{AlCl3}{Ch3Cl}> Toulene + HCl$

Step 2 : Conversion of Toluene to dinitrotoluene.

Dinitritoluene is prepared from toluene by Nitration . This reaction uses Electrophilic substitution mechanism . The reagents used are HNO₃ and H₂SO₄ at room temperature . These reagents produces NO₂⁺ ( nitronium ion ), a electrophile which attacks on C2 and C4 Carbon atoms of Toluene.

Toluene $Tolune \frac{HNO3 -H2SO4}{30-40 degree C} -> 2,4- dinitrotoluene$

Step 3) Conversion of Dinitro toluene to trinitrotoluene.

This reaction is extended nitration of toluene . Further nitration is done in extreme condition . The temperature of reaction is increased to 90- 100 ⁰ C . Due to which there is more production of NO²⁺ ion occurs from HNO₃ -H₂SO₄ and they attack on C6 carbon atom of dinitrotoluene which forms 2,4,6- trinitrotoluene.

Dinitrotoluene $2,4 -dinitrotoluene \frac{fuming HNO3-H2So4}{90-100 C} -> 2,4,6-trinitrotoluene.$

So over all reaction uses three reagents in order :

$Benzene \frac{AlCl3}{CH3Cl} -> Toluene \frac{HNO3-H2So4}{room temp} -> 2,4-dinitrotoluene \frac{Fuming HNO3 -H2SO4}{Heating at 90-100 C} -> 2,4,6-trinitrotoluene .$
