The reactivity series is a series of metal elements, and sometimes carbon and hydrogen, that is arranged according to their reactivity. A reactivity series is typically a vertically presented model with the most-reactive element placed at the top of the series and the least-reactive element placed...
Hydrogen is a non-metal but still, it has been included in the reactivity series as it helps in the comparison of reactivity of metals. The reactivity of the metals is given below in another tabular format where it has been mentioned along with its ions. Here metals are segregated in ...
Reactivity Tests & Extraction Potassium, sodium and lithium all react quickly with cold water to produce a metal hydroxide and hydrogen gas. Most metals react with dilute acids to produce a salt and hydrogen gas. Extraction of metals Most metals are only found as compounds because the metal has...

The electro positivity of the elements also reduces while moving down the reactivity series of metals. All metals that are found above hydrogen in the activity series liberate H2 gas upon reacting with dilute HCl or dilute H2SO4. Metals that are placed higher on the reactivity series have the...
hydrogen. Metals that do not react in water may react in acid. When metal reactivity is to be directly compared, a single displacement reaction serves the purpose. A metal will displace any metal lower in the series. For example, when an iron nail is placed in a copper sulfate solution, ...
A series of 18 aliphatic alcohols and their hydrogen-bonded complexes with ammonia are studied by applying density functional theory computations at the B3LYP/631G(d,p) level. Theoretically determined electronic parameters—partial atomic charges and electrostatic potential at nuclei (EPN)—are employed...

The reaction of Ru3(CO)12 with 3-2dimethybut-1-yne (t-Butylacetylene) gives the mono-hydride HRu3(CO)9C2But in good yields. This complex reacts in hydrocarbon solvents with molecular hydrogen, to give the tri-hydride H3Ru3(CO)9C·CH2·CMe3 which, upon further hydrogenation, affords H4...
A series of aliphatic alcohols, aldehydes, and ethers also react in parallel hydrogen atom and hydride transfer reactions, but acetone and acetonitrile react by hydrogen atom transfer only. Precise rate constants for each pathway for a number of substrates were obtained from a combination of ...
