Select the correct IUPAC name among the following:
- A
2-Bromo-4-chloro-3-lodopentane
- B
4-Bromo-2-chloro-3-lodopentane
- C
4 Bromo-2 iodo-3-chloropentane
- D
2-Chloro-3-iodo-4-bromopentane
The IUPAC name is determined by the following rules:
1. Number the carbon atoms in the chain, starting from the end closest to the functional group (in this case, the halogens).
2. Identify the substituents (halogens) and their positions on the chain.
3. List the substituents in alphabetical order, with their positions.
In this case, the correct order is:
- 2-Bromo (Br at position 2)
- 4-Chloro (Cl at position 4)
- 3-Iodo (I at position 3)
