Question

The structure of 2, 3-dibromo-1-phenylpentane is.
A)

B)

C)

D)

Answer 1

Hint: We know that the IUPAC nomenclature, the natural science terminology IUPAC is a technique for natural substance mixes as suggested by the International Union of Pure and Applied Chemistry (IUPAC). To keep away from long and dull names in ordinary correspondence, the official suggestions for naming IUPAC are not generally continued by and by, with the exception of when a compound must be given an unambiguous and total definition. In some cases, IUPAC names might be less complex than more seasoned names, similarly as with ethanol, instead of ethyl liquor.

Complete step by step answer:
As per the Guidelines set by IUPAC, the classification of mixes must follow these means:
1The Longest Chain Rule: The parent hydrocarbon must be recognized and in this way named. The parent bind having a place with the compound being referred to is commonly the longest chain of carbon molecules, be it as a straight chain or a chain of some other shape.
2.The Lowest Set of Locants: The carbon molecules having a place with the parent hydrocarbon chain must be numbered utilizing common numbers and starting from the end in which the least number is doled out to the carbon iota which conveys the substituents.
3.Various cases of the equivalent substituent: Prefixes which demonstrate the all out number of the equivalent substituent in the given natural mixes are given, for example, di, tri, and so on
4.The naming of various substituents present at similar situations: In the situation wherein two contrasting substituent bunches are available at a similar situation of the natural compound, the substituents are named in climbing sequential request.
5.Naming Complex Substituents: Complex substituents of natural mixes having fanned structures must be named as subbed alkyl gatherings though the carbon which is connected to the substituent bunch is numbered as one. These extended and complex substituents must be written in sections in the IUPAC classification of the relating mixes.
The structure formula of 2, 3-dibromo-1-phenylpentane is,

So, the correct answer is Option A.

Note: We have to remember that the arrangement of a deliberate name for a natural compound requires first determination and afterward naming of a parent structure. This essential name may then be altered by prefixes, infixes and on account of a parent hydride, additions which pass on definitely the auxiliary changes needed to create the compound being referred to from the parent structure. As opposed to such orderly names, there are conventional names which are broadly utilized both in industry and scholarly circles. Models are acidic corrosive, benzene and pyridine. Subsequently when they meet the necessities of utility and when they fit into the overall example of precise terminology, these customary names are held.
