C6H6 + E+(Electrophile)
C6H6E
Substitution Reaction
Which group increases the electron density of the benzene ring?
+I, +m, and +H group with benzene increase the electron density as they fastly undergo electrophilic substitution reaction.
Give an example of halogenation of benzene.
Reaction of kinetic isotopic effect
KC6H6>KC6T6>KC6D6
Give an example of sulphonation of benzene.
Desulphonation of Benzene
Give an example of nitration of benzene.
Alkylation Friedel Craft’s Reaction
C6H6 + CH3Cl → C6H6CH3 + HCl
Rearrangement of carbocation
The stability of the carbocation is as follows: 3°> 2°>1°> -CH3+
The carbocation will only rearrange it the compound is becoming more stable.
Acylation Friedel Craft’s Reaction
C6H6 + CH3COCl → (with the presence of Anhydrised AlCl3) C6H6COCH3
What are activator and deactivator compounds?
Activator compounds are the compounds in which +m effect showing groups are attached with C6H6.
Inactivator compounds is the compound with - m effect showing groups.
Gatterman Aldehyde Synthesis
C6H6 + HCl + HCN → (AlCl3/H3O+) C6H6CHO
Gatterman Koch Synthesis
C6H6 + HCl + CO → (with the presence of Anhydrised AlCl3) C6H6CHO
How is chloro benzene formed?
C6H6 + Cl → (with the presence of Anhydrised AlCl3) C6H6Cl
Benzene + CH3Cl (with the presence of Anhydrised AlCl3) →
Toulene(C6H6CH3)
