Q:-Define Boranes & its Generic formula? Ans: -In chemistry, boranes comprise a large group of compounds with the generic formula of BxHy. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The class is named after the parent chemical called "borane" itself, chemical formula BH3. This compound is only known to exist as a transient intermediate since it dimerises to form diborane, B2H6. The larger boranes all consist of boron clusters that are polyhedral. In addition to the charge-neutral boranes, a large number of anionic boron hydrides are known. The most important boranes are diborane B2H6 and two of its pyrolysis products, pentaborane B5H9 and decaborane B10H14. The development of the chemistry of boron hydrides led to new experimental techniques and theoretical concepts. Boron hydrides have been studied as potential fuels, for rockets and for automotive uses, but the only commercial applications involve derivatives of borane.

The four series of single-cluster boranes have the following general formulae, where "n" is the number of boron atoms:
