Well-known examples include the Grignard reaction, the Sabatier reaction, the Wittig reaction, the Claisen condensation, the Friedel–Crafts acylation, and the Diels–Alder reaction. Books have been published devoted exclusively to name reactions; [2] [3] [4] the Merck Index, a chemical encyclopedia, also includes an appendix on name reactions.
An online system named ePathshala, a joint initiative of NCERT and Ministry of Education, has been developed for broadcasting educational e-schooling resources including textbooks, audio, video, publications, and a variety of other print and non-print elements, [18] ensuring their free access through mobile phones and tablets (as EPUB) and from ...
The poem Sabse Khatarnak by the Hindi poet Pash was included in the NCERT textbook for 11th standard Hindi students in 2006. In 2017, the BJP government affiliated RSS tried to remove it but failed. [25] [26] The NCERT made two controversial changes to the class XII political science textbook ‘Politics in India Since Independence’ in 2017.
This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl 2), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH 2] + Cl −) with water (H 2 O). [1] [2] During the synthesis, ammonium chloride is also produced. It is a type of nucleophilic addition reaction. Stephen ...
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
The Baeyer–Villiger oxidation is an organic reaction that forms an ester from a ketone or a lactone from a cyclic ketone, using peroxyacids or peroxides as the oxidant. [1] The reaction is named after Adolf von Baeyer and Victor Villiger who first reported the reaction in 1899.
The simplified leaching reaction is given by the following chemical equation: 2 Al + 2 NaOH + 6 H 2 O → 2 Na[Al(OH) 4] + 3 H 2. The formation of sodium aluminate (Na[Al(OH) 4]) requires that solutions of high concentration of sodium hydroxide be used to avoid the formation of aluminium hydroxide, which otherwise would precipitate as bayerite.
