Worked Solution & Example Answer:The structure of pivalic acid is shown - Scottish Highers Chemistry - Question 9 - 2019
Step 1
Which of the following is the correct systematic name of pivalic acid?
Answer
To determine the correct systematic name of pivalic acid, we first analyze its structure.
Pivalic acid, also known as 2,2-dimethylpropanoic acid, consists of a propanoic acid structure with two additional methyl groups attached to the second carbon. This leads to the following breakdown:
- Identify the Parent Chain: The longest continuous carbon chain is the propanoic acid backbone, which consists of three carbons.
- Count the Methyl Substituents: There are two methyl groups on the second carbon.
- Name the Compound: The correct IUPAC name accounts for both the propanoic acid base and the substituents.
Thus, the systematic name for pivalic acid is 2,2-dimethylpropanoic acid (Option D).
