MCQ
The IUPAC name for tertiary butyl iodide is:
- A4-iodobutane
- B2-iodobutane
- C1-iodo-3-methylpropane
- D2-iodo-2-methylpropane
✓
Answer
- 2-iodo-2-methylpropane
Explanation:
There are certain steps that we follow during IUPAC nomenclature such as:
Step 1: Find and name the longest continuous carbon chain.
Step 2: Identify and name groups attached to this chain.
Step 3: Do the numbering.
Step 4: Designate the location of each substituent group by an appropriate number and name.
Step 5: Assemble the name, listing groups in alphabetical order using the full name.
So, here in this case the longest continuous chain is of 3 C so the base name would be propane.
There is a methyl group and Iodine group present at C−2 position so the substituent naming would be according to alphabetical order as; 2−Iodo−2−Methyl.
Therefore, The IUPAC name of a compound is 2−iodo−2−methylpropane.
