Benzene and phenol
Read our general notes on Risk Assessment
Why is the Kekulé structure for benzene discredited for not showing a true reflection of bonding, when it is used in academia for showing mechanisms in journals?
Ulex replies
I wish I knew! I have had one former pupil come back from Bristol University to say that he had had a stand-up row with one lecturer who persisted in using the Kekulé structure, and numerous others who reported scorn being poured on the hexagon-with-circle representation. I believe there is a slow move in favour of the latter amongst younger lecturers. Put it down to natural conservatism or even a sort of badge-of-honour, as if to say: 'I have now become a 'proper' chemist instead of a beginner!'
An alternative view
You will find that Rod Beavons takes a different view and justifies the use of the Kekulé structure.
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
