What is a magnet?
A magnet is a material or artificial setup that can produce a magnetic field around it. Due to the magnetic field, a magnet can attract ferromagnetic materials (e.g. iron filings) and attract or repel any other magnet. Magnets, suspended through a string, always point towards the north-south directiRead more

See lessHow glycine can be prepared by strecker synthesis?
In situ ATR-FTIR spectroscopy characterizations reveal a favorable tandem pathway on the dual-site catalyst. Specifically, the Pb site drives the highly selective electroreduction of H2C2O4 to form glyoxylic acid, and the Cu site accelerates the fast hydrogenation of oxime to form a glycine product.

See lessWrite short note on Claisen rearrangement.
Claisen rearrangement is an organic chemical reaction that offers a powerful method of the formation of carbon-carbon bonds. The reactant of this reaction – allyl vinyl ether, is converted into a gamma, delta-unsaturated carbonyl compound when subjected to heat or a Lewis acid.

Williamson’s Synthesis;
The reaction of alkyl halides with Sodium alkoxide or Sodium phenoxide to form Ether is called Williamson synthesis.
See lessIt is a process that allows the preparation of a wide range of symmetric and asymmetric Ethers by a
mechanism.
In Williamson’s synthesis, the Alkyl halide is heated with alcoholic Sodium alkoxide then the Alkoxide ion is a nucleophile that displaces a Halide ion from an alkyl halide to give an ether.
Primary Alkyl halides will give a better yield.
This method is used for both basic and mixed Ether preparation.
Example:
Methyl iodide is heated with alcoholic Sodium ethoxide then the ethoxide ion acts as a nucleophile which displaces an iodide ion from an methyl iodide to give an Ethyl methyl ether
Write notes on Reimer-Tiemann reaction.
When phenol reacts with chloroform in the presence of bases ( N a O H / K O H ) , an aldehyde ( − C H O ) group gets introduced in the ring at a position ortho to the phenolic group and salicylaldehyde is formed. This reaction is called the Reimer-Tiemann reaction.

Why is a Baori called stepwell?
Stepwells (also known as vavs or baori) are wells, cisterns or ponds with a long corridor of steps that descend to the water level. Stepwells played a significant role in defining subterranean architecture in western India from the 7th to the 19th century.
