Photoactivated ketones show strong potential as hydrogen atom transfer photocatalysts, enabling the activation of carboxylic ...

Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

Chemistry students are taught that hydrogen bonds and covalent bonds are distinct, but a new study shows they exist on a continuum.

Researchers recently discovered a form of hydrogen bond so strong it's comparable to the covalent bonds binding hydrogen and oxygen together into water molecules within the droplet.

Hydrogen bonds give water its special properties and even hold our very DNA together. Scientists have just seen them through a microscope for the first time.

Figure 1: Examples of triple hydrogen-bond arrays and their association constants in various solvents. Figure 6: UV/vis competition experiment in which 13 is displaced from 12·13 by a large ...

Instructions 1 Engage Step 1 Show an animation to introduce the process of covalent bonding. Introduce the question students will investigate in this lesson: If atoms have an equal number of protons ...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope.

Logically, the larger the number of Hydrogen cargoes shipped, the greater the number of disputes which will arise – for example, collisions, contractual breaches and insurance to name but a few.

The first step, however, is very, very difficult -- breaking the carbon-hydrogen bond. A new au naturel catalyst mimics nature to break the tenacious C-H bond.
