Which structure is 3-ethyl-2,4-dimethylhexane?
The Correct Answer and Explanation is :
The structure shown in the image for 3-ethyl-2,4-dimethylhexane can be understood by following the systematic IUPAC naming rules.
Explanation:
- The parent chain here is hexane, which consists of six carbon atoms (C6H14).
- The numbering of the carbons begins from one end of the chain, giving the lowest possible locants to the substituents.
- At carbon 2, there is a methyl group (–CH3).
- At carbon 3, there is an ethyl group (–C2H5).
- At carbon 4, there is another methyl group (–CH3).
Breakdown of the name:
- “Hexane” is the base name, indicating a six-carbon alkane chain.
- The “dimethyl” part indicates two methyl groups (–CH3) attached to the chain at positions 2 and 4.
- The “ethyl” part indicates an ethyl group (–C2H5) attached to the chain at position 3.
- The numbers 2, 3, and 4 indicate the positions of these substituents along the carbon chain, ensuring the lowest locants for the substituents are used.
Structure:
Here’s the structure for 3-ethyl-2,4-dimethylhexane:
- A six-carbon straight chain (hexane) with:
- A methyl group at position 2,
- An ethyl group at position 3,
- A methyl group at position 4.
I will now generate the image of this structure.
Here is the chemical structure for 3-ethyl-2,4-dimethylhexane, showing the hexane chain with the substituents (methyl and ethyl groups) attached at the appropriate positions. If you have any more questions or need further details, feel free to ask!
