Infrared (IR) spectroscopy and catalysis represent two of the most practically relevant topics in chemistry, but they are normally taught in separate contexts at the undergraduate level. Although IR spectroscopy is introduced to students as a tool for organic compound characterization, it also finds wide applicability in the investigation of…

Laboratory safety has received heightened attention due to a series of devastatingly tragic accidents in both academic and nonacademic settings. Consequently, chemistry departments at various academic institutions now offer some form of formal training in laboratory safety for entering graduate students. Although the extent of this training varies…

Recently, topical products advertising cannabinoid ingredients have gained popularity. Consumers are seeing an increase of commercial products containing ingredients from hemp oil to cannabidiol (CBD) due to health benefit claims. Cosmetic products containing cannabinoids are currently not regulated at the federal level. A laboratory experiment…

Oxidation reactions are critical components of the synthetic toolbox taught to undergraduate students during introductory organic chemistry courses. However, the oxidation reactions discussed in the undergraduate curriculum are often outdated as many organic chemistry textbooks emphasize chromium-based oxidants that are no longer in regular use by…

Organic chemistry students often struggle with reaction mechanisms, particularly in how they are proposed and justified. In this activity targeting second year organic undergraduates, students used infrared spectroscopy (IR) to track the reaction progress of two distinct aldol reactions and used polarimetry to analyze the stereoselectivity of…

Active learning is known to improve student outcomes in many STEM courses. Here, we present strategies for incorporating active learning into a large enrollment General Chemistry I course using small group activities during class time. This approach was found to mitigate gender disparities in overall course grades and reduced the number of General…

The inclusion of the InChI or SMILES codes as a one-sentence answer allows web-based classroom response systems to provide instant feedback to some of the most typical drawing-based questions asked in organic chemistry courses. This paper discusses the implementation and scope of this strategy using smartphones as the only hardware requirement.

A laboratory experiment has been devised to train new graduate trainees in the safe and controlled handling of air-sensitive organometallic reagents using Schlenk lines, high vacuum pumps, liquid nitrogen traps, and cannula transfers. The reaction involves the formation of air-, moisture-, and thermally sensitive 2-pyridyllithium, generated in…

Over the past two and a half years, the COVID-19 pandemic severely disrupted almost all aspects of life as people throughout the world were instructed to work-from-home. Scientific researchers, whose work is reliant on access to laboratory equipment, have been acutely impacted by these global changes. In this study, we surveyed graduate students…

Student learning and course performance are often improved when students actively engage with content. However, pedagogical practices that foster active engagement often rely on student-student and student-instructor interactions that may be difficult to adapt to an online environment. Here we describe a Collaborative Learning program that…

In this review article, formulae based innovative mnemonics have been discussed to create interest and remove phobia of students in the field of inorganic and organic chemistry. Educators can use these numerous mnemonics in their teaching style in the classroom lectures after discussing conventional methods to make chemistry intriguing. Here, I…

Completion of a first-semester chemistry (Chem I) course lays the foundation for understanding second-semester chemistry (Chem II) topics. The purpose of this study is to evaluate the influence of basic arithmetic skills on students' Chem II success in understanding mathematics-grounded concepts (e.g., solutions and aqueous reactions, kinetics,…

Herein, we describe a simple laboratory experiment to address nanomaterial synthesis, plasmon resonance, and its application to detect Cu[superscript 2+] in ultralow concentrations. The proposed experiment is very visual and appealing for chemistry students, especially the undergraduate-level chemistry major. In this experiment, the aggregation of…

Wide accessibility and a broad range of applications have made 3D-printers a commonplace tool in the science community. From tier-one research institutions to community public libraries and high schools, 3D-printers are being used to enrich STEM education through a variety of learning techniques and experiences. Reports of 3D-printed models for…

Fundamentals of Macroscopic Chemical Analysis is a newly developed foundation-level course that integrates concepts from traditional physical and analytical chemistry courses. The course was designed to serve majors in chemistry, biochemistry, and biology as well as pre-health professional students. The main goal of this course is to develop the…
