The Subject

The paper analyzes fifteen organic chemistry textbooks commonly used in Brazilian universities to examine intermolecular forces’ coverage in them. The findings revealed that the intermolecular forces are spread over a few pages (less than 1%) in a fragmented way, and over several chapters that do not provide enough information to help create a clear image in the student’s mind. Thirteen textbooks contained end-of-chapter problems related to intermolecular forces. However, less than 1.3% of the total (212) are associated with intermolecular forces. This deficient approach to intermolecular forces in Organic textbooks can lead to teachers’ lack of interest in teaching the subject, leading to students failing to learn this important organic chemistry topic

Illustrated with remarkable new full-color images--indeed, one or more on every page--and written by one of the world's leading authorities on the subject, Reactions offers a compact, pain-free tour of the inner workings of chemistry. Reactions begins with the chemical formula almost everyone knows--the formula for water, H2O--a molecule with an "almost laughably simple chemical composition." But Atkins shows that water is also rather miraculous--it is the only substance whose solid form is less dense than its liquid (hence ice floats in water)--and incredibly central to many chemical reactions, as it is an excellent solvent, being able to dissolve gases and many solids. Moreover, Atkins tells us that water is actually chemically aggressive, and can react with and destroy the compounds dissolved in it, and he shows us what happens at the molecular level when water turns to ice--and when it melts. Moving beyond water, Atkins slowly builds up a toolkit of basic chemical processes, including precipitation (perhaps the simplest of all chemical reactions), combustion, reduction, corrosion, electrolysis, and catalysis. He then shows how these fundamental tools can be brought together in more complex processes such as photosynthesis, radical polymerization, vision, enzyme control, and synthesis. Peter Atkins is the world-renowned author of numerous best-selling chemistry textbooks for students. In this crystal-clear, attractively illustrated, and insightful volume, he provides a fantastic introductory tour--in just a few hundred colorful and lively pages - for anyone with a passing or serious interest in chemistry.

The Subject

The flipped classroom is a pedagogical approach that moves course content from the classroom to homework, and uses class time for engaging activities and instructor-guided problem solving. The course content in a sophomore level Organic Chemistry I course was assigned as homework using video lectures, followed by a short online quiz. In class, students' misconceptions were addressed, the concepts from the video lectures were applied to problems, and students were challenged to think beyond given examples. Students showed increased comprehension of the material and appeared to improve their performance on summative assessments (exams). Students reported feeling more comfortable with the subject of organic chemistry, and became noticeably passionate about the subject. In addition to being an effective tool for teaching Organic Chemistry I at a small college, flipping the organic chemistry classroom may help students take more ownership of their learning.

Free Radical Chemistry

For many years, an introduction to the chemistry of free radicals has formed an essential part of University chemistry curricula and the subject is of wide relevance to both industrial and biological chemistry, yet its development occurred, with surprising rapidity, less than fifty years ago. It is the aim of this article to give a personal recollection of the circumstances which led to the recognition and early development of this branch of chemistry. From the early days of the last century ‘radicals’ had been defined by chemists as ‘groups of atoms which together behave as a single atom’ and organic chemistry had been regarded as the chemistry of ‘compound radicals’. But with the proof that such simple elements as hydrogen, oxygen and nitrogen exist as binary molecules (H 2 , O 2 , N 2 ) and not as atoms, the possible existence at room temperature, in gases or solutions, of free atoms or radicals was deemed to be unlikely by most chemists of a century ago.

It may be remembered that, in the paper formerly laid before this Society on this subject, I endeavoured to establish the principle still disputed by some physiologists, that the laws which regulate the chemical relations, as well as those which regulate the visible movements of the particles of matter, undergo a certain determinate modification or change in living bodies, which is essential to the commencement and to the maintenance of the organization of those bodies; and farther, that I undertook the task of attempting to deduce, from the numerous but somewhat discordant experiments and observations lately made on the subject, certain inferences which appear to be well ascertained, although not generally admitted, as to the essential nature of this change, i. e., as to laws which regulate those chemical actions which are peculiar to the state of life, and essential to the maintenance of organization, both in vegetables and animals.

Long Term Retention

Organic chemistry is a subject which students find difficult because of complex reactions and mechanisms involved. The main aim of this study was to study the students' understanding of the concepts of organic chemistry by pattern based teaching method (PBT). Pattern Based Teaching is a systematic approach in teaching chemistry where the reactions and mechanisms are systematized into a particular pattern for different functional groups. The students are made to understand the basic concepts how to introduce a particular functional group and how functional groups give reactions with different type of reagents. The present paper reports the effect of this innovative teaching method on students' long term retention of organic chemistry course material. Long term retention of contents was examined by conducting two tests-pretest (based on traditional lecture teaching) and a post-test (conducted after PBT). Students' of first year undergraduate class of two different colleges of Kishangarh city of Ajmer district of Rajasthan were used for the study. These students were divided into six groups and two of them were taught by the author by PBT method. The rest four groups were control groups taught by the traditional lecture based teaching method. Students performance after PBT method was compared to that in a traditional lecture based teaching method. Our analysis showed that the out of the six sample groups of students used in our study, the highest mean scores (10.46 and 13.36) were of the two experimental groups. The four control groups had mean scores in the range 7-10. This investigation thus suggests that pattern-based teaching in organic chemistry is a powerful and systematic approach which facilitates students’ long-term retention of contents of the subject. It promotes active learning and creates students’ interest in the subject.

Learning stereochemistry today, especially on the topic of conformational stability, seems to generalize anti, gauche, eclipsed conformations as a general stability order for all acyclic organic molecules. This may be due to the fact that many organic chemistry textbooks only emphasis simple non-polar molecules, like propane or buthane, as examples to explain this topic omitting details for polar ones. This study proposes a simple computer-based technique as a project for students in learning stereochemistry. Applying this fast, open-source, and user-friendly software is highly recommended for promoting the concept and accurately predicting of conformational stability through computer-assisted experiment in the classroom.
