Hydrogen forms molecular compounds with p-block elements (B, C, N, O, F; Si, P, S, Cl; Ga, Ge, As, Sb, Br; In, Sn, Sb, Te, I; Tl, Pb, At). The common examples of such hydrides are CH3, NH3, H2O, HF etc.  

Covalent hydrides are classified as electron rich, electron precise and electron deficient hydrides.

(a) Electron rich molecular hydrides: These hydrides have one or more lone pairs of electrons around the central more electronegative element. For example

     ��              ��              ��

H � O � H, H � N � H, H � F:

     ��              |               ��

                     H

(b) Electron precise molecular hydrides: Elements of group 14 form such hydrides. The bond length increases on going down the group. A common example of electron precise molecular hydrides is CH4.

(c) Electron deficient molecular hydrides: These hydrides have lesser number of electrons than that required for writing the conventional Lewis structure. A common example of such molecular hydride is diborane, B2H6.

(d) Systematic names of molecular hydrides: The systematic names of these hydrides are obtained from the name of the element and the suffix �ane. For example,

      PH3           H2O          NH3

  Phosphane   oxidane        ozane

The covalent hydrides with an example:

  • When a hydrogen atom and one or more non-metals create a compound, covalent hydrides are generated.
  • This happens when hydrogen forms covalent connections with more electropositive detail by sharing electron pairs.
  • Volatile and non-volatile hydrides are both possible.
  • Without a doubt, a volatile method can easily be vaporized at low temperatures.
  • While hydrogen interacts with chlorine to generate hydrochloric acid, this is an example of a covalent hydride (HCl).
  • Because of their solubility in common solvents, they are utilized in organic synthesis.

For example

Sodium borohydride.
