Therefore, insight into chemical bonding can inspire new materials with properties we have yet to imagine. Synthetic materials such as computer chips, plastics, cosmetics, textiles and medicines come from making and breaking chemical bonds. How are charge-shift bonds applied in the real world? Chemical bonding is at the heart of chemistry, so changing the way chemists think about bonding will change the entire field. This is the first major change in the way chemists think about bonding in more than 100 years. By trying to understand why, Shaik and Hiberty uncovered something completely unique. Traditionally thought of as a purely covalent bond, this molecule didn’t behave like any other covalent bond. Chemistry is all about pattern recognition, and all of the bonds they studied fit a well-established pattern, except the bond between two fluorine atoms.

Shaik and Hiberty were calculating the energy required to break a series of bonds using a method called valence bond theory. The speed at which you move through the airport is not due to standing or walking, but a combination of both.Īlong with Shaik, Hiberty and a handful of others around the world, I have helped show that charge-shift bonding is a broad phenomenon that happens between a variety of elements from across the periodic table. Now suppose that someone realized that there is a third way to move: You can stand on the walkway and walk at the same time.
That might sound a little crazy, but think of it like this: You know those movable walkways at airports? Suppose that for over 100 years, people thought that the only way to get from one point to another was to either stand on the moving walkway or walk alongside it.
In charge-shift bonds, electrons are both shared and transferred at the same time. What makes a charge-shift bond different? The charge-shift bond of the fluorine molecule showing electron depletion in the bonding region.
