There are certain species in organic reactions that are formed during the course of the reaction and are responsible for directing the reactions in forward direction. One of such species is the enolate which is generally formed during the reaction and is highly reactive....
What chemical elements are found in proteins? What are semi-volatile organic compounds? What is an enolate in organic chemistry? What is an enantiomer in organic chemistry? What is a diol in organic chemistry? What is a stereocenter in organic chemistry?
The arc discharge method is the main method for producing Carbon Black. The specific process of the arc discharge method is: place the graphite electrode in a reaction vessel filled with helium or argon gas, and stimulate an arc between the two electrodes. At this time, the temperature can r...

Steric hindrance at a given atom in a molecule is the congestion caused by the physical presence of the surrounding ligands, which may slow down or prevent
Dealkylation would give the phosphoryl enolate. The driving force of the reaction could then be the preference of phosphorous to be bonded to oxygen rather than carbon would drive this equilibrium toward the enol phosphate. Logged Author of a multi-tiered example based workbook for learning ...
There is another very common situation where sp2geometry is observed, however. If adjacent atoms have single electrons in unhybridized p-orbitals, and if those p-orbitals can overlap, a bond can result. This is a phenomenon known as “pi-bonding“. (We’ll have a lot more to say about ...
