Electron rich hydrides

N H 3 is electron rich hydride. Describe electron-rich hydride. Which of the following hydrides is an electron-rich hydride? Name two electron rich hydrides.

Hydrides - Hydrides are the binary compound of hydrogen with other elements. Let 'X" be any element, then -. Ex - MgH 2 is the hydride of Magnesium. Based upon the number of electrons and bond type covalent or molecular hydrides are classified into -. So, match each hydrides accordingly we get, a - iv , b - i , c - ii , d - iii.

Electron rich hydrides

Define the following terms: a electron-deficient b electron - precise c electron-rich compound. Justify your answer with an example? Example: CH 4 , SiH 4 , etc. What do you understand by i electron-deficient, ii electron-precise, and iii electron-rich compounds of hydrogen? Provide justification with suitable examples. Byju's Answer. Open in App. Electron deficient: Electron-deficient compounds are those compounds that don't have a sufficient number of electrons to complete the octet of the central atom. These compounds contain insufficient numbers of electrons to form normal electron-pair bonds between each pair of bonded atoms. Electron deficient compounds exist in polymorphic forms to complete their electron deficiency. Example: The compounds containing less than 8 electrons in the valence shells are called electron-deficient compounds such as B 2 H 6 , AlH 3 , etc. Electron precise : Electron precise compounds of hydrogen contain sufficient valence electrons to form covalent bonds.

These extra electrons are either in form of lone pairs or -ve charge. BIS Technical Assistant.

Hydrides are binary compounds of hydrogen. In which hydrogen remain as the anion or negatively charged ion H —. Its general formula is MH x or M x H y. Metals of groups- 7, 8 and 9 hardly form hydrides and thus the region group- 7 to 9 in periodic table is known as hydride gap. These hydrides are formed when hydrogen combines with elements which possess electronegativity value lower than that of hydrogen 2. Thus all alkali metals and alkaline earth metals can form ionic hydrides by transferring one electron from the metal ion to hydrogen atom.

Electron rich hydrides

Hydride , in simple terms, is said to be the anion of hydrogen. It is a chemical compound where the hydrogen atoms exhibit nucleophilic, basic or reducing properties. Compounds of hydrogen with less electronegative elements are known as hydrides. So, when hydrogen reacts with any other element, the product formed is considered to be a hydride.

At one extreme, all compounds containing covalently bound H atoms are called hydrides: water H 2 O is a hydride of oxygen , ammonia is a hydride of nitrogen , etc. For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element.

JK Police Constable. Indian Army Nursing Assistant. ISRO Assistant. Which of the following elements occur freely in nature? MP Police Constable. Chhattisgarh Junior Engineer. The valence electron in Ge is 4 and 4 electrons are shared from the four hydrogens and hence have a complete octet. UK Police Constable. Punjab Pre-Primary Teacher. NVS Stenographer. Electron deficient: Electron-deficient compounds are those compounds that don't have a sufficient number of electrons to complete the octet of the central atom.
