hydrides of group 14

Expert Answer
The elements of the group 14 form the covalent hydrides of type MH4. The number of the hydrides and their thermal stability also the ease of their formation decreases with we move from top to down in the group. From CH4 to PbH4 the reducing power increases. The carbon forms the large number of the cyclic and the acyclic hydrides known as the hydro carbons. Similarly Si and Ge also form hydrides of the general formula MnH2n+2. The thermal stability decreases as we go down because of the increases in the size of metal. There bond length increases and because of that the bond strength decreases and it results decreases in thermal stability.
