This is a discussion prompt where students find a molecule they use in a personal care product, cleaning product, or processed food. They find the structure, relate components of the name to aspects of the structure, look up the product on the Environmental Working Group (EWG) or FDA websites, and look up the molecule in PubChem. At the end, they need to decide whether they are happy with their ...

An organic chemistry laboratory experiment illustrating the oxidation of primary and secondary alcohols to their corresponding aldehyde or ketones, respectively, is described.

In this experiment, students perform a Grignard reaction under air-free conditions to synthesize and isolate organometallic Ni(II) phosphine complex(es) that are used as pre-catalysts for a Suzuki-Miyaura Coupling reaction in tert-amyl alcohol.

One of the main advantages of doing green chemistry is that it can often be done on the benchtop without the need for a fume-hood. In this experiment water and ethanol are the only solvents used for both the reaction and purification steps and oxone is a safe oxidant whose only by-product is potassium sulfate.

The oxidation of aromatic aldehydes using oxone allows instructors to discuss green ...

A new green oxidation procedure was developed for the undergraduate organic teaching laboratories using Oxone and a catalytic quantity of sodium chloride for the conversion of borneol to camphor. This simple 1 h, room temperature reaction afforded high quality and yield of product, was environmentally friendly, and produced negligible quantities of hazardous waste. The experiment was performed ...

Applications of organic chemistry to modify the structure and surface properties of materials are becoming increasingly important and interdisciplinary as the dimensions of modern materials decrease.

The subjects of the modules are based on winners of the Green Chemistry Challenge Awards. The modules ...

The purpose of this lab is to introduce students to some basics of the chemistry of polymers. Polymer chemistry is often an afterthought in the General Chemistry curriculum, but polymers are very much present in students’ lives. The lab introduces the relationship between molecular structure (e.g., branched vs. linear, bulky vs small side groups) and bulk properties (e.g., flexibility). This lab ...

The purpose of this lab is to give students experience in the practical preparation of buffers and exploring buffer properties. Students will prepare aqueous solutions with specific concentrations of acids and bases, and use pH meters to examine the pH of these buffers.

We have an ongoing plastic problem. This is not news, but also not the end of the story.

Half of the plastics being produced are single-use plastics, meaning they are only intended to be used once. Compared to how long plastics take to break down, or degrade, there is a large time difference between the time the product is in use versus the time the product degrades.

Plastics are made up of ...

There are many tools that a synthetic organic chemist can use to synthesize amines; one of which is reductive amination. This common method of introducing the amine functionality is especially crucial for the synthesis of pharmaceuticals and biomolecules.

A typical reductive amination is a one-pot reaction involving a solvent, an aldehyde or ketone, an amine, and a weakened reducing agent. This ...
