Organic chemistry: smelly and difficult?

Organic chemistry can appear unattractive to some students at first glance. The terminology it uses can make some see it as a difficult section of chemistry to understand. Fears of the subject area can then be compounded by the complexity of some organic compounds, the requirement to visualise them in 3D and a perceived need to rote learn lots of information. But there are many ways to help students see organic chemistry in all its glory.http://www.rsc.org/eic/2014/07/organic-chemistry-teaching-learning

Student difficulties

Carbon-based materials are all around us and the diversity of these makes the study of carbon compounds both interesting and confusing. The very word organic has several meanings which may be more familiar to students, referring to the way some food products are produced or to living materials. The terminology we use can be a barrier to learning as students struggle with a whole new ‘language’ of specific terms which, designed to systematise nomenclature, can muddy the waters as we introduce new names for familiar materials. Ethanoic acid for acetic acid and poly(ethene) for polythene, for example. ‘Old’ names persist in industry and in some areas of higher education simply because they are familiar and short and yet the dictates of examinations mean we have to help students to grapple with this whole new language.

Selective fluorination of alkyl C–H bonds via photocatalysis

We report the generation of cationic N-radicals from Selectfluor® via energy transfer with anthraquinone as a photocatalyst for the fluorination of unactivated C–H bonds.
