Which one of the following is the best name according to IUPAC system for the compound with the formula shown below?
Correct answer: B. 2-chloro-4-methyl heptane
- A. 4-methyl-6-chloro heptane
- B. 2-chloro-4-methyl heptane
- C. 2-chloro-4-n propyl hexane
- D. 2-chloro-4-n propyl pentane
Explanation
The longest carbon chain is 7 carbons long and has only single carbon-carbon bonds hence heptane.The numbering would favour chloro group over the methyl group, hence 2-chloro-4-methyl heptane.

About Nomenclature, Structure and Reactivity
Alkyl halides are named by selecting the longest carbon chain and locating the halogen substituent, while their structures are classified as primary, secondary or tertiary. Their reactivity includes nucleophilic substitution and elimination, with the behaviour of leaving groups and the distinction between SN1 and SN2 mechanisms linked to substrate structure.
