- 2-chloro but-3-chloride
- but-2,3-dichloride
- 2, 3-dichlorobutane
- 3-chloro but-2-chloride
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The structure of the compound is CH₃–CH(Cl)–CH(Cl)–CH₃. This is a four-carbon straight chain alkane (butane) with chlorine atoms on the second and third carbon atoms. According to IUPAC naming conventions:
- The parent chain has 4 carbon atoms → butane
- Two chlorine substituents are attached → prefix "di" is used
- Their positions are on carbon 2 and 3 → locants are 2,3
The correct option is (C): 2, 3-dichlorobutane
