Question

What is the IUPAC name of this compound:

Answer 1

(1) IUPAC name: 4,4-dimethylpentoic acid

(2) common name: m-bromobenzoic acid

​​​​​

Step 1: Identify the longest carbon chain. This chain is called the parent chain. Step 2: Identify all of the substituents (groups appending from the parent chain) Step 3: Number the carbons of the parent chain from the end that gives the substituents the lowest numbers Step 4: If the same substituent occurs more than once, the location of each point on which the substituent occurs is given. In addition, the number of times the substtuent group is indicated by a prefix (di, tri, letra, etc.) The name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain). Commas are used between numbers and dashes are used between letters and numbers. There are no spaces in the name.
