name the organic priduct obtained when benzene is treated with excess of chlorine in presence of anhydrous aluminium chloride
Answers
Answer:
chloro benzene is formed as substituents in place of hydrogen.
The organic product obtained when benzene is treated with excess of chlorine in presence of anhydrous aluminium chloride
Explanation:
Aromatic Compounds
1. It Means aroma (pleasant smell.)
2. They have benzene ring C₆H₆(alternate 3 double bond with no benzene ring).
3. All with benzene ring is called are called Benzenoid compound and with no benzene ring is called Non-benzenoid compound ).
• In benzene
- The double bonds keep on moving so, the structure showing double bond can be written in either ways. It has no effect on the chemical reactions of benzene .
- Or we can say that pi electrons keeps moving i.e. shifting of π electron takes place. Therefore basic structure of Benzene can be written as shown below .The Hybridisation is sp² .
- Structure of benzene is planar with sp² hybridisation .
- To see stability we can calculate enthalpy of hydrogenation.
- Or we can say that pi electrons keeps moving i.e. shifting of π electron takes place. Therefore basic structure of Benzene can be written as shown below .The Hybridisation is sp² .
- Substitution Reaction - In this hydrogen is going to get substituted by some other group.
For example :
Halogenation : Substitution by halogen like chlorine
The Mechanism involved is electrophilic substitution mechanism.
Ist step : Formation of electrophile
2nd step : Attack of electrophile on benzene ring
Order of halogenations : For fluorine it is quite fast and also leads to explosion Fluorine > Chlorine > Bromine > Iodine
3. Deprotonation : removal of proton
The main reaction along with steps of mechanism is attached below .
