Hydride A binary compound of hydrogen

Hydride. A binary compound of hydrogen with some other element. 

CH2=CH2 + H20 - CH3CH2OH. hydride A binary compound of a metal or metalloid with. hydrogen the term is often extended to include all binary compounds of hydrogen. A saline or saltlike hydride is a compound of hydrogen and a strongly electropositive metal a molecular hydride is a compound of hydrogen and a nonmetal a metallic hydride is a compound of certain d-block metals and hydrogen. 

Hydride a binary compound containing hydrogen. The hydride ion, H, exists in ionic hydrides. The three classes of hydrides are covalent, interstitial, and ionic. (18.3) Hydrocarbon a compound composed of carbon and hydrogen. (22.1)... 

The Preparation of a Hydride.—Strictly speaking, a hydride is the binary combination of hydrogen with a more positive element (metal) but for convenience we shall use the term to denote any binary compound of hydrogen. In addition to a number of methods applicable in special cases, there are two general methods available in the preparation of hydrides. The most general one is the direct union of hydrogen with another element, thus ... 

Hydrocarbon. A binary compound of carbon and hydrogen a general term which includes the paraffin, olefin, aromatic, and all other series of hydrides of carbon. 

Hydrogen is a nonmetal. All binary compounds of hydrogen are covalent., except for certain metal hydrides such as NaH and CaH2y which contain hydride, H, ions. 

The periodic trends in main-group elements become apparent when we compare the binary compounds they form with one specific element. All the main-group elements, with the exception of the noble gases and, possibly, indium and thallium, form binary compounds with hydrogen, so these hydrides can be examined to look for periodic trends. We meet the binary hydrides several times in this chapter and the next, so, at this stage, we confine the discussion to a brief survey and see how their properties reveal periodic behavior. 

The Compounds of Hydrogen. Hydrogen forms binary compounds with all of the metalloids and non-metals except the noble gases. (A binary compound is a compound of only two elements.) It also combines with many of the metals. The compounds of hydrogen with metals and metalloids are called hydrides other compounds of hydro-... 

The hydrides formed in reaction (a) may be classified as (1) saline or ionic hydrides, (2) metallic hydrides and (3) covalent hydrides. The saline hydrides include the hydrides of the alkali and alkaline-earth metals, except BeHj, which is covalent. Transition metals form binary compounds with hydrogen that are classified as metallic hydrides including rare-earth and actinide hydrides. Intermetallic compound hydrides, such as TiFeHj and LaNijH, may be thought of as pseudobinary metallic hydrides. 

Rule 6 The oxidation state of hydrogen in a compound is usually +1. If the hydrogen is part of a binary metal hydride (compound of hydrogen and some metal), then the oxidation state of hydrogen is -1. 

Write a balanced equation for the preparation of (a) an ionic hydride and (b) a binary molecular compound of hydrogen. 

Figure 11.24A shows a plot of boiling point versus molecular weight for the hydrides (binary compounds with hydrogen) of the Group VIA elements. If London... 

Chemically, hydrogen behaves as a typical nonmetal, forming covalent compounds with other nonmetals and forming salts with very active metals. Binary compounds containing hydrogen are called hydrides, of which there are three classes. The ionic...
