Answer 1

1. The Wurtz reaction, named after Charles Adolphe Wurtz, is a coupling reaction in organic chemistry, organometallic chemistry and recently inorganic main group polymers, whereby two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane. As an example, we can obtain ethane by reacting methyl bromide with sodium in the presence of anhydrous ether or tetrahydrofuran. Here, a large alkane molecule is developed by the joining two compound of alkyl halide and eradicate the halogen atoms in the
2. An alkyl group can be added to a benzene molecule by an electrophile aromatic substitution reaction called the Friedel‐Crafts alkylation reaction. One example is the addition of a methyl group to a benzene ring. ... An electrophile is formed by the reaction of methylchloride with aluminum chloride.
3. Organosilicon compounds successfully synthesized via the Wurtz–Fittig reaction include silylated calixarenes, t-Butylsilicon compounds, and vinylsilanes. For example, t-butyltriethoxysilane can be prepared via the Wurtz–Fitting reaction by combining tetraoxysilane, t-butyl chloride and molten sodium.
4. The reaction mechanism involves a two-stage radical process: electrochemical decarboxylation gives a radical intermediate, which combine to form a covalent bond. As an example, electrolysis of acetic acid yields ethane and carbon dioxide: CH3COOH → CH3COO− → CH3COO· → CH3· + CO. 2CH3· → CH3CH.form of sodium halide.
