Name each disubstituted benzene. c.

검증된 단계별 안내

Identify the substituents on the benzene ring. In this case, the substituents are bromine (Br) and chlorine (Cl).

Determine the positions of the substituents on the benzene ring. The bromine is at position 1 and the chlorine is at position 4.

Since the substituents are at positions 1 and 4, this is a para-disubstituted benzene.

Name the substituents alphabetically. Bromine (bromo) comes before chlorine (chloro).

Combine the substituent names with the position and the base name 'benzene' to get the final name: 1-bromo-4-chlorobenzene.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Disubstituted Benzene

Disubstituted benzene refers to a benzene ring that has two substituents attached to it. The positions of these substituents can significantly affect the chemical properties and reactivity of the compound. The naming of disubstituted benzenes follows specific rules based on the relative positions of the substituents, which can be ortho (1,2), meta (1,3), or para (1,4).

Nomenclature of Aromatic Compounds

The nomenclature of aromatic compounds, particularly disubstituted benzenes, follows the IUPAC system. The substituents are named in alphabetical order, and the position of each substituent is indicated by numbers. For example, in a compound with bromine and chlorine, the name would reflect the positions of these groups on the benzene ring, such as 1-bromo-2-chlorobenzene for ortho substitution.

Electrophilic Aromatic Substitution

Electrophilic aromatic substitution is a fundamental reaction mechanism in organic chemistry where an electrophile replaces a hydrogen atom on an aromatic ring. The presence of substituents can influence the reactivity and orientation of further substitutions due to their electronic effects, such as activating or deactivating the ring. Understanding this concept is crucial for predicting the outcomes of reactions involving disubstituted benzenes.
