Question

What is the correct IUPAC name for the following compound?

A. $3,4-\dim ethyl-3-n-propy\ln onane$
B. $6,7-\dim ethyl-2-n-propy\ln onane$
C. $6,7-\dim ethyl-7-ethyldecane$
D. $4-ethyl-4,5-\dim ethyldecane$

Answer 1

Hint: Each natural compound has a special, unambiguous name. The IUPAC name of any compound passes on the design of that compound to an individual acquainted with the framework. One method of checking whether the name you have given to an alkane is sensible is to tally the quantity of carbon molecules suggested by the picked name.

Complete answer:
We have to remember that hydrocarbons having no twofold or triple bond utilitarian gatherings are delegated alkanes or cycloalkanes, contingent upon whether the carbon iotas of the atom are masterminded distinctly in chains or likewise in rings. Albeit these hydrocarbons have no useful gatherings, they comprise the structure on which useful gatherings are situated in different classes of mixtures, and give an optimal beginning stage to examining and naming natural mixtures. The alkanes and cycloalkanes are additionally individuals from a bigger class of mixtures alluded to as aliphatic. Basically, aliphatic mixtures are intensified that don't consolidate any sweet-smelling rings in their atomic construction.
IUPAC rules for alkane nomenclature has to be given,
Find and name the longest ceaseless carbon chain.
Distinguish and name bunches appended to this chain.
Number the chain successively, beginning toward the end closest to a substituent bunch.
Assign the area of each substituent bunch by a suitable number and name.
Collect the name, posting bunches in sequential requests.
The prefixes di, tri, tetra and so forth, used to assign a few gatherings of a similar kind, are not viewed as while ordering.
Therefore, the correct IUPAC name of the given compound is $4-ethyl-4,5-\dim ethyldecane$

So, the correct answer is “Option D”.

Note:
We need to know that in rundown, the name of the compound is worked out with the substituents in sequential request followed by the base name (derived from the quantity of carbons in the parent chain). Commas are utilized among numbers and runs are utilized among letters and numbers. There are no spaces in the name.
