Concept explainers
(a)
Interpretation:
Structural formula for methyl thiopropanoate has to be drawn.
Concept Introduction:
General structure of thioester can be represented as shown below,
From an IUPAC name, the structure of the thioester can be derived. IUPAC name of thioester consists of two parts. In an IUPAC name of thioester, the first part of the name is the alkyl part and the second part is the acid part. Alkyl group have come from the thiol and acyl part from
The same rule applies for deriving a structure from common name. The only difference is the acyl part name. The acyl part is named using the common name of thiocarboxylic acid.
