Controlling electronic 1 and/or nuclear 2,3 motion in molecules using external fields represents, at the moment, the ‘holy grail’ of chemistry. More than half a century ago, the 1966 Nobel Prize ...

If phosphorous has five electrons in its outermost shell, meaning it needs only three more to fill the shell, how can it form FOUR valence bonds when used as a dopant in a silicon crystal? This is one ...

The chapter Chemical Bonding plays an important role in IIT JEE, UPSEE, WBJEE and various other engineering entrance examinations. This article talks about Valence Shell Electron Pair Repulsion (VSEPR ...
