Sure, let's break down the name "2, 3-diethyldec-4-yne" step by step to understand its chemical structure and composition.
1. Dec-4-yne: This is the base name of the molecule.
- "Dec-" refers to a 10-carbon atom chain, meaning the main carbon chain has 10 carbons.
- "4-yne" specifies a triple bond (≡) at the 4th carbon atom.
2. 2, 3-diethyl: This prefix indicates that there are ethyl groups (-C2H5) attached to the main carbon chain.
- "di" means there are two ethyl groups.
- These ethyl groups are located at the 2nd and 3rd carbon atoms of the main chain.
Now let's put all this information together to describe and draw the structure:
1. Carbon Chain:
The main carbon chain is 10 carbons long:
[tex]\[
\text{C-C-C-C-C-C-C-C-C-C}
\][/tex]
2. Triple Bond:
A triple bond begins at the 4th carbon. So, the chain will be:
[tex]\[
\text{C1-C2-C3-C4≡C5-C6-C7-C8-C9-C10}
\][/tex]
3. Ethyl Groups:
Ethyl groups are attached to the 2nd and 3rd carbons:
[tex]\[
\begin{array}{c}
\text{C1-C2-C3-C4≡C5-C6-C7-C8-C9-C10} \\
| | \\
C2H5 C2H5 \\
\end{array}
\][/tex]
Here is a more organized depiction of the structure:
- Carbons are numbered:
[tex]\[
\text{C1 - C2 - C3 - C4 ≡ C5 - C6 - C7 - C8 - C9 - C10}
\][/tex]
- Ethyl groups attached to C2 and C3:
[tex]\[
\begin{array}{c}
\text{C2H5 | C2H5} \\
\text{ \\ } \\
\text{C1 - C2 - C3 - C4 ≡ C5 - C6 - C7 - C8 - C9 - C10}
\end{array}
\][/tex]
To summarize:
- The molecule is based on a 10-carbon chain.
- A triple bond is located between the 4th and 5th carbons.
- Ethyl groups (-C2H5) are attached to the 2nd and 3rd carbon atoms of the main chain.
