In chemical bonding: Electron-deficient compounds Another type of exception to the Lewis approach to bonding is the existence of compounds that possess too few electrons for a Lewis structure to be written. Such compounds are called electron-deficient compounds. A prime example of an electron-deficient compound is diborane, B2H6.… Read More

In chemical bonding: The role of delocalization …outstanding problem is that of electron-deficient compounds, as typified by B2H6. Such molecules are classified as electron deficient because, in Lewis terms, there are fewer than two electrons available per bond. However, a consequence of delocalization is that the bonding influence of an electron pair is distributed over all the… Read More
