Question

What is the IUPAC name of this compound?

Answer 1

Hint- In order to determine the IUPAC name of given carbon structure first we will understand what is the process to give an IUPAC name of any carbon structure then according to it we will write the IUPAC name of given structure.

Complete answer:
Here is simple list of rules to follow to write the IUPAC name of any carbon structure
1. Identify the longest carbon chain. This chain is called the parent chain.
2. Identify all of the substituent (groups appending from the parent chain).
3. Number the carbons of the parent chain from the end that gives the substituents the lowest numbers. The sequence which is the "lowest" when comparing a set of numbers is the one which includes the lowest number at the first discrepancy. When there are two or more side chains in equal positions, allocate the lowest number to the one that appears first in the description.
4. When the same substituent occurs more than once, the position is given for any point where the substituent occurs. Further, a suffix (di, tri, tetra, etc.) specifies the number of times the substituent group exists.
5. If there are two or more different substituents they are listed in alphabetical order using the base name (ignore the prefixes).
Apart from these rules there are some more rules as well.
Now, given compound is:
Here from the structure we find the number of carbon in longest chain is 7 so the name Heptane, we will then see for the substituents as there are two ethyl group at 3rd and 4th carbon so the name diethyl also there is a methyl group at 4th carbon, so the name methyl.

Hence, the IUPAC name of the given compound is 3,4-diethyl-3-methyl Heptane.

Note- The IUPAC nomenclature of organic chemistry is a system of organic chemical compounds in chemical nomenclature, as defined by the International Union of Pure and Applied Chemistry (IUPAC). It is written in the Organic Chemistry Nomenclature (informally also known as the Blue Book). Ideally a conceivable organic compound would have a name from which to construct an unmistakable structural formula. Some of the rules are mentioned in the solution, students must remember these rules in order to name a compound.
