What is a synthon in chemistry?
In retrosynthetic analysis, a synthon is a hypothetical unit within a target molecule that represents a potential starting reagent in the retroactive synthesis of that target molecule. The term was coined in 1967 by E.
What is FGI in chemistry?
An approach for designing organic synthesis which involves breaking down of target molecule into available starting material by imaginary breaking of bonds (disconnection) and/ or by functional group interconversion (FGI) is known as disconnection approach or retrosynthetic analysis or retrosynthesis or synthesis …
Which statement best describes a synthon?
Which of the following statements best describes a synthon? (1 Point) A synthetic reagent used in a reaction A key intermediate in a reaction sequence A transition state involved in a reaction mechanism A hypothetical structure that would result in a given reaction if it existed.
What is difference between synthon and reagent?
Reagent: A compound which reacts to give an intermediate in the planned synthesis or to give the target molecule itself. The synthetic equivalent of a synthon. Synthetic equivalent: A reagent carrying out the function of a synthon which cannot itself be used, often because it is too unstable.
What is acceptor synthon?
(b) Acceptor Synthons: These are positively polarized synthons denoted by symbol ‘a’. Common donor synthons. Synthetic equivalents. Common donor synthons.
Which of the following statements best describes a synthon?
Why is retrosynthesis important?
Retrosynthesis is the deconstruction of the target organic compound, which is complex into its simple forms of precursors. However, it is done on a paper, not done chemically. Thereby, the main importance of retrosynthesis is that it helps to identify the route of synthesis of the target organic compound.
In retrosynthetic analysis, a synthon is a destructural unit within a molecule which is related to a possible synthetic operation. The term was coined in 1967 by E. J. Corey. He noted in 1988 that the “word synthon has now come to be used to mean synthetic building block rather than retrosynthetic fragmentation structures”.
What is a synthon in retrosynthetic analysis?

Who coined the term synthon?
The term was coined in 1967 by E. J. Corey. He noted in 1988 that the “word synthon has now come to be used to mean synthetic building block rather than retrosynthetic fragmentation structures”.
Are there equivalent chemical compounds to synthons in real life?
Since synthons are idealized structures, it is often difficult to find equivalent chemical compounds in the real world. Many carbanion synthons, as drawn, present stability issues that render the molecule’s existence in reality impossible.
