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

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. ... (for example, in water), ...

Note: This model of covalent bonding for the hydrogen molecule (H 2) starts with 2 individual hydrogen atoms. In reality, hydrogen atoms are never separate to start with. They are always bonded with ...

A research team led by Prof. Pan Feng from the School of Advanced Materials, Peking University Shenzhen Graduate School has ...

The experimental trends are less clear cut for quadruple hydrogen-bond complexes (see, for example, 9·9 and 10·11, Fig. 2).However, there are far fewer examples of such arrays, and with a small ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two.

Hydrogen bonds directly detected for the first time Date: May 12, 2017 Source: Universität Basel Summary: ... for example, also ensure that water has a high boiling temperature. ...

A new catalyst for breaking the tough molecular bond between carbon and hydrogen holds the promise of a cleaner, easier, cheaper way to derive products from petroleum, say researchers. Simple ...
