Question

Draw the structure for $\mathbf{4}\mathbf{\text{-ethyl-}}\mathbf{2}\mathbf{,3}\mathbf{\text{-isopropylpentane}}$. This name is incorrect. Give the correct systematic name.

Short answer

The correct name is $4-\text{isopropyl}-\; 2,3,5-\text{trimethyl}\text{heptane}$.

Step-by-step solution

Define the structural isomers.

Structural isomers are those in which the atoms are organized in a different order but have the same molecular formula.

The structural isomers are isomers that differ in the atomic arrangement of molecules without any reference to the spatial arrangement. Structural isomerism is the term for the phenomena of structural isomers.

Define the correct name of hydrocarbons.

The provided name is incorrect based on the structural presentation.

The longest chain was not picked as a parent chain; in this construction, the parent chain is "hept,"and the numbering should be done according to the lowest sum rule.

Begin from the right side:

Its skeletal structure is

Thus, the correct name is $4-\text{isopropyl}-2,3,5-\text{trimethyl}\text{heptane}$.
