Schiff's reaction and Tischenko reaction
(a) Schiff's reaction: this reaction restores pink colour to Schiff's reagent (aqueous solution of p-rosaniline hydrochloride decolourised through passing sulphur dioxide).
(b) Tischenko reaction: On heating benzaldehyde along with aluminium alkoxide (ethoxide) and a little of anhydrous AlCl3 or ZnCl2, it goes through an intermolecular oxidation and reduction (such as aliphatic aldehydes) to make acid and alcohol respectively like and react to produce benzyl benzoate (an ester).

Q. Determine Mass to charge ratio of the electron? Ans. Eventually, Thomson was able to find the ratio of the electron's mass to its electrical charge (m/e). Regardless o
SOME EXAMPLES FOR ANTI-FERTILITY DRUGS
Q. Show the Structure of sulphuric acid? Theoretical considerations require that the reaction be carried out at low temperature and high pressure. However, at low temperature,
Acetic acid has less conductivity, due to it ionizes less in solution. HCl divides almost completely in solution to form the ions Cl- and H+..
