Hydrogen double displacement reaction

When acids and bases come into contact with one another, a chemical reaction called a neutralization reaction takes place. A neutralization reaction is a double displacement reaction. In a double displacement reaction, the positive ions from one reactant take the place of the positive ions in the other reactant. For example, if hydrochloric acid and sodium hydroxide react with one another, the positive sodium ion in sodium hydroxide will take the place of the hydrogen ion in the hydrochloric acid ... 

Remember that an acid-base reaction is a double displacement reaction. Therefore, if sulfuric acid and potassium hydroxide are mixed, the positive ions trade places. The hydrogen ions from the sulfuric acid will react with the negative hydroxide ions to form water. Because a hydrogen ion has a charge of + 1 and a hydroxide ion has a charge of -1, they bond in a 1 1 ratio ... 

Because this is a reaction between an acid and a base, it will be a double displacement reaction, and the positive ions will switch places. The potassium ion will react with the sulfate ion, forming the salt potassium sulfate (K2S04). And the hydrogen ion in the acid will react with the hydroxide ion in the base to form HOH, or water (H20). 

Fe is the chemical symbol for iron. It comes from iron s Latin name, Ferrum. In this reaction, the iron in iron oxide (Fe2Os) switches places with the hydrogen in the hydrochloric acid (HCl). Double displacement reactions are like two pairs of dancers switching partners. 

In the double displacement reaction above, dissolved sodium cyanide (NaCN) and sulfuric acid (H2S04) react to form sodium sulfate (Na2S04) and an extremely poisonous gas called hydrogen cyanide (HCN). The (aq) means these substances are an aqueous solution. An aqueous solution is made by dissolving chemicals in water. In this reaction, the sodium cyanide, sulfuric acid, and sodium sulfate are all dissolved in water. The (g) that follows the formula for hydrogen cyanide indicates that this chemical is a gas. The hydrogen cyanide will bubble out of the solution, leaving behind the sodium sulfate that is still dissolved in the water. 

Acid-base reactions are a special type of double displacement reaction. Acid-base reactions occur when an acid and a base react with one another. An acid is a compound that contains hydrogen and gives off hydrogen ions (H+) when it is dissolved in water. Bases, on the other hand, produce hydroxide ions (OH ) when they are dissolved in water. 

This reaction could be viewed in terms of a double displacement reaction One of the oxygen atoms and one of the hydrogen atoms have displaced each other. One of the most famous examples of this type of exchange reaction, a single exchange, occurs between iron oxide and aluminum ... 

Neutralization reactions are a special type of double displacement reaction that produces water. Neutralization involves the reaction of an acid with a base to form water and an ionic compound. You will learn more about neutralization reactions in Chapter 10. For example, the neutralization of hydrogen nitrate (nitric acid) with sodium hydroxide (a base) is a double displacement reaction. 

Hydrogen fluoride, HF, is a highly toxic gas. It is produced by the double displacement reaction of calcium fluoride, CaF2, with concentrated sulfuric acid, H2S04. 

A neutralization reaction is a double-displacement reaction of an acid and a base. Acids are compounds that can release hydrogen ions bases are com-poxmds that can neutrafize acids by reacting with hydrogen ions. The most common bases are hydroxide and oxide compounds of the metals. Normally, an acid reacts with a base to form a salt and water. Neutrafization reactions occur because of the formation of the very stable covalent water molecule, H2O, from hydrogen and hydroxide ions. 

In some double-displacement reactions, one of the products is an insoluble gas that bubbles out of the mixture. For example, iron(II) sulfide reacts with hydrochloric acid to form hydrogen sulfide gas and iron(II) chloride. 

The me.vo-diphcnylphospholanomide was obtained via a cycloaddition reaction of N,N-d -methylaminophosphinodichloride and 1,4-diphenylbutadiene followed by hydrogenation. The mcw-compound was transformed into an equilibrium mixture containing predominately the rac-compound on treatment with base. After hydrolysis, the phospholanic acid was kinetically resolved using quinine. Reduction and protection of the phospholane as the borane adduct allowed the double displacement of 1,2-ethyleneglycol ditosylate.

Bisphosphine chiral auxiliaries have been prepared by stereoselective double displacement of a seven-membered cyclic sulfate with 1,2-bis(phosphino)ethane in the presence of n-BuLi (91JA8518) (Scheme 73). Similarly, l,2-bis(phosphino)benzene gave bisphosphine 290 (Scheme 73). These chiral auxiliaries have proved to be powerful ligands in a stereoselective hydrogenation reaction (95JA4423). 

Amino-3-deoxy-sucrose has been synthesized from sucrose by sequential oxidation at C-3 by Agrobacterium tumefaciens (40% yield), peracetylation, reduction of the C-3 ketone to an a//o-configured product (H2, Pt), trifluoro-methanesulfonylation, displacement by azide with inversion, deacetylation and hydrogenation. 4-Amino-4-deoxy-sucrose was obtained from a sucrose hepta-pivaloate by double inversion at C-4 by sequential triflate displacement reactions, first with nitrite then azide ion. Various 4-alkylamino-2,4-dideoxy-L-r/ireo-pentopyranosides 15, components of the calicheamicins, were synthesized from...
