A laboratory experiment in which [superscript 1]H NMR and UV-vis spectroscopies are applied to probe the temperature dependence of a monomer-dimer equilibrium involving a cyclopentadienone derivative is described and discussed. Details of the data analysis for extraction of equilibrium constants from the raw experimental data from both techniques…

A convenient approach to obtain Lewis structures for compounds of the type YX[subscript n] involves first constructing a trial structure that satisfies the valence of the outer atoms (e.g.,1 bond for fluorine, 2 bonds for oxygen, and 3 bonds for nitrogen)and placing the molecular charge (if any) on the central atom. The second step involves…

Despite tremendous efforts by instructors and textbook authors, students find it difficult to develop useful chemical intuitions about structures and key properties of the important d-block organometallic species that have a d[superscript 6], d[superscript 8], or d[superscript 10] d-electron count. A full molecular orbital analysis is not always…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

Interdisciplinary integration is an inevitable trend in the development of science and technology, as well as the reform and development of higher education. With the rapid development of biomaterials in the pharmaceutical and medical industries, many undergraduate students in chemistry and materials science have been focusing on life sciences as…

The mechanistic approach to teaching introductory-level organic chemistry--Organic One and Two (Organic I and II) in the United States--continues to predominate since its introduction through Morrison and Boyd's legendary textbook. In this approach, reactions are taught alongside their electron-pushing mechanisms (EPMs), thereby providing students…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

A one-pot regio- and stereoselective synthesis of a dipyrromethane and a bis(indolyl)methane based on two consecutive reactions of nitrosoalkenes with pyrrole or indole, respectively, is described as an experiment to be carried out by upper-division undergraduate students in a laboratory classroom. Importantly, the ability of electrophilic…

This study is a follow up to two earlier studies characterizing student real-time use of mechanistic arrows. In these previous studies, students were asked to predict a product by drawing a curved arrow mechanism using an interface that allowed recording and replay of student actions. In the present study two different student cohorts responded to…

The ability to reason with representations is pivotal for successful learning in Organic Chemistry and is closely linked to representational competence. Given the visual nature of this discipline, this comprises competency in extracting and processing relevant visual information. With regard to the resonance concept, proficiency in identifying…

Energy is a crosscutting concept in science, but college students often perceive a mismatch between how their biology and chemistry courses discuss the topic. The challenge of reconciling these disciplinary differences can promote faulty reasoning--for example, biology students often develop the incorrect idea that breaking bonds is exothermic and…

Organic chemistry is challenging for novices as it involves a large quantity of organic reactions. Effective learning requires not only profound theoretical knowledge but also the ability to reason about causal mechanisms. This study investigated pre-service chemistry teachers' mechanistic reasoning and the implicit cognitive process. Participants…

Since ancient times, man has prepared medicines and used them in healing practices. Therefore, there has always been a great interest in the part of people in general and students in particular about medicines. The "Medicines, the Haute Couture of Pharmacy" summer camp has the objective to promote and improve the literacy in medicines…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Academic integrity is one of the significant issues facing assessments in higher education. While there are a plethora of papers addressing this problem in certain locales, very little research has been published regarding tertiary institutions in the Caribbean. This paper satisfies this paucity in the literature and present findings which will…
