    When two enantiomers are mixed in equal proprtion they cancell out each others activity making the overall mixture inactive .The mixture thus formed is racemic mixyure and the process is known as racemisation. For eg .Butan-2-ol

    The Wurtz reaction is a very useful reaction in the fields of organic chemistry and organometallic chemistry for the formation of alkanes. In this reaction, two different alkyl halides are coupled to yield a longer alkane chain with the help of sodium and dry ether solution.

    This reaction is named after the French chemist Charles Adolphe Wurtz, who also discovered the aldol reaction. Apart from sodium, metals like silver, indium, activated copper, zinc, and iron can also be used in the Wurtz reaction in order to obtain alkanes.

    The mechanism of this reaction involves free radicals, allowing for the possibility of side reactions that lead to the formation of alkenes as the product. A reaction related to the Wurtz Reaction in which aryl halides are used instead of alkyl halides is often called the Wurtz-Fittig reaction and is a very important named reaction in organic chemistry.

    Wurtz Reaction Equation

    The general form of the Wurtz reaction equation can be written as follows:

    2R-X + 2Na → R-R + 2Na+ X–

    It can be observed from this equation that the two R groups are joined, yielding an alkane with a longer chain along with NaX, where X is a Halogen.

    Thermal stability refers to the stability of a compound in presence of heat. If a compound is thermally unstable, then it decomposes easily in the presence of heat. If a compound is thermally stable, then it doesn't decompose easily in the presence of heat.

    Because phenols are stabilised by the delocolaisation of pi electrons over the entire benzene ring. Thus in the resonating structures of phenols O gets Positively charged,and thus facilitates the release of H positive ions.
