   C{{H}_{3}} \\
\end{matrix}CHO $ ?

Answer 1

Hint: The growing number of organic compounds found each day, along with the fact that many of these compounds are isomers of other compounds, necessitates the development of a systematic naming system. Each individual compound must be given a characteristic and unique name, just as each distinct compound has a unique molecular structure that may be denoted by a structural formula.
As organic chemistry progressed, several substances were given incomprehensible names that are now widely used and recognised.

Complete answer:
The IUPAC nomenclature system is a set of logical criteria developed and utilised by organic chemists to avoid the issues that arbitrary naming may bring. Knowing these criteria and being provided a structural formula, one should be able to write a separate name for each compound. Similarly, given an IUPAC name, a structural formula should be able to be written. An IUPAC name will, in general, contain three characteristics:
A root or base in a chemical structure that denotes a large chain or ring of carbon atoms.
A suffix or other element(s) indicating the presence of functional groups in the compound.
Other than hydrogen, these are the names of substituent groups that complete the molecular structure.
Alkanes and cycloalkanes are hydrocarbons with no double or triple bond functional groups, depending on whether the carbon atoms of the molecule are organised in chains or rings. Despite the fact that these hydrocarbons lack functional groups, they serve as a framework for the placement of functional groups in other classes of compounds, and they are an excellent beginning point for researching and identifying organic molecules.
First, we give a number to each carbon atom in such a way that the functional group receives the least number. We begin with the aldehyde group, therefore the methyl group will be on the second carbon atom, and so on.
The numbering system is $ {{C}^{(3)}}{{H}_{3}}\begin{matrix}
   Br \\
   \underset{|}{\overset{|}{\mathop{-\text{ }{{C}^{(2)}}-}}}\, \\
   C{{H}_{3}} \\
\end{matrix}{{C}^{(1)}}HO $
2-bromo-2-methyl propanal is the IUPAC nomenclature for $ C{{H}_{3}}\begin{matrix}
   Br \\
   \underset{|}{\overset{|}{\mathop{-\text{ }C-}}}\, \\
   C{{H}_{3}} \\
\end{matrix}CHO $ .

Note:
An aldehyde is a chemical molecule that contains a functional group with the structure CHO, which consists of a carbonyl centre (a carbon double-bonded to oxygen) and a carbon atom that is additionally linked to hydrogen as well as any generic alkyl or side chain R group. An aldehyde or formal group is a functional group that exists without the "R" side chain.
Aldehydes, which are formed by removing a hydrogen from an alcohol, are prevalent in organic chemistry; formaldehyde being the most well-known. Many perfumes are or include aldehydes because they are usually intensely fragrant.
