Aromatic hydrocarbons or arenes: their definition, types, nomenclature, and reactions.
Translated by Google. Click to view original.
Aromatic hydrocarbons or arenes:They are organic hydrocarbon compounds that contain at least one benzene ring.
Gasoline:
It is the simplest aromatic compound.
The molecular formula of benzene is C6H6
The structural formula of gasoline is a regular hexagonal ring containing 6 identical carbon atoms connected to six hydrogen atoms. Inside the ring there are 3 double bonds interchangeable with 3 single bonds that are not centered in a specific position in what is called resonance.
The first person to establish the structural formula for gasoline was the scientist August Kekulé, who suggested that gasoline has two formulas due to resonance.
Resonance in gasoline makes it lower in energy and therefore more stable
Resonance in benzene affects its chemical activity, making it more likely to react by substitution than by addition.
Preparation of gasoline
It is prepared in industry from destructive distillation of coal and from the polymerization of acetylene gas or the reduction of phenol.
It is prepared in the laboratory by dry distillation of anhydrous sodium benzoate salt by heating it with soda lime.
Benzene reacts in addition only with hydrogen (catalytic hydrogenation), forming cyclohexane, and also with chlorine in direct sunlight and high temperature, forming hexachlorocyclohexane.
Benzene tends to react by electrophilic substitution, such as halogenation, sulfonation, nitration, alkylation, and acylation.

AQA A-level biology exam preparation and content tutoring sessions“Biology at A-level is nothing like GCSE” , believe me I know. I understand how overwhelming the jump from GCSE biology to A-level biology can be. As a first year university student who has completed my biology A-level in the summer, I’ve been through the challenges you’re all facing and I’m here to help you overcome them. In my tutoring sessions we will focus on:
- mastering any topics from the AQA specification you guys are unsure about, breaking them down into easy to understand concepts and focusing on parts you need to know for your exam.
- practice exam questions in every session with detailed feedback to sharpen your exam technique and to know what the examiners are looking for.
-EFFECTIVE revision techniques which will help you retain any key bits of information.
Each session will leave you confident in biology, ensure you build a strong understanding of the topic and feel prepared for your exams.
