The reduction of aromatic compounds by alkali metals in liquid ammonia represents an important method for the preparation of partially unsaturated six-membered rings. Birch Reduction Reaction is an organic reaction which is used to produce cyclohexadienes from aromatic compounds. It is named after an Australian Chemist, Mr. Arthur John Birch, who reported it in In this reaction, we use 3 reagents, namely – 1) Liquid Ammonia (NH 3), 2) Organic Alcohol (ROH) and 3) Alkali metal (Li, Na or K). Arthur. The Birch reduction is an organic reaction that is used to convert arenes to reaction is named after the Australian chemist Arthur this organic reduction of aromatic rings in liquid ammonia with sodium, lithium, or potassium and an alcohol, such as ethanol and reaction is unlike catalytic hydrogenation, which usually reduces the aromatic ring all Organic Chemistry Portal: birch-reduction. Alkali metals belong to the s-block elements occupying the leftmost side of the periodic metals readily lose electrons, making them count among the most reactive elements on earth. In this article, we will explain the electronic configurations, ionization enthalpy, hydration enthalpy and atomic, ionic radii and other physical and chemical properties of the group one alkali metals.

The chemistry of lithium, sodium, and potassium in liquid ammonia and in liquid solutions of low molecular weight amines such as methyl- and ethylamine and the reactions of organic compounds in these solutions have been discussed quite thoroughly in several critical reviews and monographs (Smith, ; House, ). On the other hand, the blue.   Solutions of Metals in Liquid Ammonia Compounds with Carbon Complexes, Crowns and Crypts Biological Importance Differences Between Lithium and the Other Group 1 Elements Preparation of Sodium Hydroxide Electrolytic Processes Preparation of Sodium Carbonate The Solvay (or Ammonia – Soda) Process. The simpilicity and efficacy of the method is illustrated by the reduction of a variety of compound groups including carbonyl compounds, aromatic and heteroaromatic rings, aryl halides, phenols. Alkaline Earth Metals have their s-subshell filled with 2 valence electrons. Understand properties, electronic configuration, analogous behavior, reactivity, ionization energy of group 2 alkaline earth metals.

We give a review of the most significant experimental properties and theoretical interpretations. We present a quantitative approach of a model in which all valence electrons are in a metallic.   Alkali metal, any of the six elements of Group 1 (Ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).
