The synthesis of a commercial fragrance, methyl cinnamate, via Fischer esterification was evaluated for use as a second-year organic chemistry course. The experiment utilizes "trans"-cinnamic acid, a commercial flavoring that possesses a mild honey floral odor, as an inexpensive starting material. Both the starting material and the…

Biodiesel is an important biomass, largely employed in the transport sector and produced from vegetable oils. Additionally, waste cooking oils may be reused to produce biodiesel fuel, minimizing environmental pollution. A laboratory experiment that affords a widespread way to discuss degradation concepts and tools for used vegetable oil…

The mental models students have after engaging in an activity designed to teach infrared (IR) spectroscopy without reliance on IR absorption tables, were characterized. Qualitative analysis of semi-structured interviews, through open coding, allowed the classification of the mental models as Molecules as Dynamic (MAD), Bonds as Dynamic (BAD),…

Carbohydrates are an essential group of molecules to the organic chemistry classroom providing molecular relevance to a common ingredient in chemical biology. While the meticulous elucidation of the carbohydrate structures by Fischer and others is an engaging topic in the lecture, there are few laboratory experiments that can emulate carbohydrate…

A modular and target-group oriented online video library with 48 videos was developed and produced in order to reduce the complexity of an introductory organic chemistry laboratory class. The library comprises three different types of videos: "Tutorials" explaining fundamental laboratory techniques, "Do nots" pointing students…

A continuous flow photopinacol coupling of benzophenone has been developed and implemented in the undergraduate laboratory. This photoreduction was accomplished using 2-propanol as an H atom donor and cosolvent in the reaction. The simple and inexpensive UV light source and flow reactor design (less than $350/photochemical flow system) provide an…

Williamson ether experiments are commonly performed by students in undergraduate organic chemistry instructional laboratory courses. In this multioutcome experiment, students were provided 4-bromophenol and one of three alkyl halides: 1-bromopentane, 1-bromobutane, or 1-bromo-3-methylbutane. The alkyl halides served as the unknown component of the…

The American Chemical Society (ACS), Division of Chemical Education, Examinations Institute, has been developing content maps to describe comprehensively the undergraduate curriculum aligned to traditional subdisciplines. These content maps have been developed through the combined efforts of many faculty members who teach the targeted courses in…

How well does the undergraduate organic chemistry laboratory curriculum prepare students for academic research, or for a bench job in industry? Running experiments that are more representative of research chemistry has the potential to better equip students for working in a research laboratory, while at the same time giving them insight into a…

An undergraduate organic chemistry experiment has been developed that features asymmetric synthesis of an enantioenriched secondary alcohol, followed by determination of its absolute configuration using the competing enantioselective conversion (CEC) method. Students are given a ketone and an unknown enantiomer of CBS (Corey-Bakshi-Shibata)…

The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

The ability to communicate scientific concepts to expert and nonexpert audiences is an essential skill for chemistry and STEM students. Current chemistry curricula mainly focus on developing skills to communicate technical information to expert audiences, while relaying the same information to general audiences receives much less attention.…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

Visualizing molecular conformations and complex compound structures and chemical transformations in 3D is one of the most difficult tasks for undergraduate chemistry students. Modern computational technologies have revolutionized every aspect of our lives, including education. As a result, many researchers and educators are working on enhancing…

In this paper, we describe a study on tasks following the construct of school-related content knowledge. We know from previous studies that such tasks were rated by the preservice chemistry teachers as important for their future profession. Those studies were conducted in a traditional course on organic chemistry which was organized around…
