difference between Ionic hydrides and covalent gives any 4 and 5 points
Answers
Ionic hydrides are formed by the complete transfer of electron between two atom . while, covalent hydrides are formed by the sharing of electron between two atom.
Answer:
Ionic or saline hydride, is a hydrogen atom bound to an extremely electropositive metal, generally an alkali metal or alkaline earth metal. In these materials the hydrogen atom is viewed as a pseudohalide. In this group, the hydrogen acts as the hydride ion (H−).Ionic hydrides are usually binary compounds (i.e., only two elements in the compound) and are also insoluble in solutions.
Properties are:
These are white crystalline solids and their crystal structures consist of ions
They have high melting and boiling points
They have high heat of formation
Uses: Ionic hydrides and their complexes are used as reducing agents. They are used as solid fuels.
This occurs when hydrogen covalently bonds to a more electropositive element by sharing electron pairs. These hydrides can be volatile or non-volatile.
Properties are:
They are usually volatile compounds having low melting and boiling points
Hydrides of group 13 do not have sufficient electrons to form covalent bonds and are called electron-deficient hydrides
Hydrides of group 14 have exact number of electrons to form covalent bonds and are called electron-precise hydrides
Hydrides of group 15, 16, 17 have more electrons to form covalent bonds and are called electron-rich hydrides
Uses:Hydrides that are soluble in common solvents are widely used in organic synthesis. Particularly common are sodium borohydride (NaBH4) and lithium aluminium hydride
