What are hydrides how are they classified explain with examples?
It is a chemical compound where the hydrogen atoms exhibit nucleophilic, basic or reducing properties. Usually, in a hydride, the hydrogen has the oxidation number equal to −1. Some of the most popular examples include water (H2O), methane (CH4) and ammonia (NH3).
On what basis are the molecular hydrides classified?
Molecular hydrides are classified as electron deficient, electron precise and electron-rich compounds.
What are the properties of hydrides?
Typically covalent hydrides have low melting and boiling points. Since the compounds bound to hydrogen are more electronegative than hydrogen these compounds are more likely to react forming a hydrogen cation (a hydrogen with a positive charge) instead of the hydrogen anion that ionic hydrides form.
What are hydrides in organic chemistry?
Hydride: (1) A hydrogen atom with a negative formal charge, H:- (the hydride ion), or a compound containing this ion. (2) A molecule with one or more bonds between hydrogen and elements less electronegative than hydrogen (i.e., a molecule that delivers hydride to another molecule).
What are metallic or interstitial hydrides?
Metallic hydrides (also known as interstitial hydrides) involve hydrogen bonds with transition metals. The idea and basis for this is that with metal and hydrogen bonding there is a crystal lattice that H atoms can and may fill in between the lattice while some might, and is not a definite ordered filling.
Is NaH a saline hydride?
NaH is a saline (salt-like) hydride, composed of Na+ and H− ions, in contrast to molecular hydrides such as borane, methane, ammonia, and water.
How are molecular hydrides classified on the basis of electrons and bonds in the Lewis structure?
Molecular hydrides are classfied on the basis of the relative number of non-bonded pair of electrons and bonds in their lewis structures.
What are molecular hydrides give example?
Example – Lithium Hydride (LiH), Sodium Hydride (NaH), Potassium hydride (KH). 2) Molecular hydride: These kinds of hydrides are formed by electron-rich compounds (generally p-block elements). 3) Interstitial hydride: These are also known as metallic halides. This type of halide is generally formed by d-block elements.
What type of hydrides is formed by group 2 elements?
Answer: The second category of hydrides are ionic hydrides (also known as saline hydrides or pseudohalides). These compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements. In this group, the hydrogen acts as the hydride ion (H−).
What is the structure of B2H6?
B2H6
Diborane/Formula
Are hydrides organic or inorganic?
For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element.
What are metallic hydrides how do they differ?
Metal hydrides have high thermal and electrical conductivity whereas the molecular hydrides have low thermal and electrical conductivity. Metallic hydrides are found in solid state whereas the molecular hydrides are comparatively soft & volatile.
