검증된 단계별 안내1
Identify the longest continuous carbon chain in the molecule. Here, the chain consists of 4 carbon atoms, which corresponds to 'butane' as the parent hydrocarbon.
Number the carbon atoms in the chain starting from the end nearest to the substituent to give the substituent the lowest possible number. Since there is a bromine (Br) substituent, number the chain from the end closest to the bromine atom.
Determine the position of the bromine substituent on the carbon chain based on the numbering. The position number indicates which carbon the bromine is attached to.
Combine the position number, substituent name, and parent chain name to form the IUPAC name. The substituent 'bromo' is placed before the parent name 'butane' with a hyphen separating the position number and substituent.
Write the full IUPAC name as: \(\text{position number}\)-bromo\(\text{parent hydrocarbon}\), for example, \(1\)-bromobutane if bromine is on the first carbon.
