Concept explainers
(a)
Interpretation:
The IUPAC name of the given compound is to be assigned.
Concept introduction:
The systematic naming of organic compound is given by IUPAC. The naming of organic compound is done in such a way that the structure of organic compound is correctly interpreted from the name.
Rules for writing the structural formula from IUPAC are:
• First identify the word root for the given compound.
• The suffix used in the compound like –ane, ene, yne, ol, al and so on.
• Identify the position, location, and number of the substituent bonded to the carbon chain.
Answer to Problem 14.5E
The IUPAC name of the given aldehyde is ethanal.
Explanation of Solution
The given compound is shown below.
Figure 1
The given compound is aldehyde. The first step in the naming of aldehyde is finding of longest parent chain that contains a carbonyl group. The second step is changing of -e ending of the parent alkane to the suffix -al. The third step is numbering of chain to give the least number to carbonyl carbon, and using the general rules of nomenclature.
The given structure shows the presence of two
The given aldehyde is ethanal.
