The IUPAC name of Neo-pentyl chloride is _____
Options
- A2-chloro 2-methyl propane
- B1-chloro-2, 2-dimethyl propane
- C1-chloropropane
- D1-chloro 2-methyl propane
Correct answer
B. 1-chloro-2, 2-dimethyl propane
Step-by-step solution
The structure of neo-pentyl chloride is CH₃-C(CH₃)₂-CH₂-Cl . The longest continuous carbon chain containing the carbon bonded to the chlorine atom has 3 carbon atoms. Numbering the chain from the end closer to the chlorine atom, the chlorine is at position 1 and two methyl groups are at position 2 . Thus, the IUPAC name is 1-chloro-2,2-dimethylpropane. Answer: 1-chloro-2, 2-dimethyl propane
