Sure, let's carefully complete the table by adding the missing structure diagram for the Ketone functional group.
1. Identify the Functional Groups and Their Structures:
- Alcohol is represented by the structure [tex]\([R]O\)[/tex].
- Ether is represented by the structure [tex]\([R]O[R]\)[/tex].
- Ketone is the missing structure that we need to identify.
- Aldehyde is represented by the structure [tex]\([R]C=O\)[/tex].
- Carboxylic Acid is represented by the structure [tex]\([R]C(=O)O\)[/tex].
- Ester is represented by the structure [tex]\([R]OC([R])=O\)[/tex].
2. Determine the Structure for the Ketone Functional Group:
- Ketones are characterized by a carbonyl group ([tex]\(C=O\)[/tex]) where the carbonyl carbon is bonded to two alkyl or aryl groups (substituents denoted as [tex]\([R1]\)[/tex] and [tex]\([R2]\)[/tex]).
- Therefore, the general structural representation for a ketone is [tex]\([R1]C(=O)[R2]\)[/tex].
3. Add the Ketone Structure to the Table:
- Simply insert the identified ketone structure diagram at the appropriate location in the table.
The completed table then looks as follows:
[tex]\[
\begin{tabular}{|c|c|c|c|c|c|}
\hline
Alcohol & Ether & Ketone & Aldehyde & \begin{tabular}{l}
Carboxylic \\
acid
\end{tabular} & Ester \\
\hline
\begin{tabular}{l}
\textless smiles\textgreater[R]O\textless/smiles\textgreater
\end{tabular} &
\begin{tabular}{l}
\textless smiles\textgreater[R]O[R]\textless/smiles\textgreater
\end{tabular} &
\begin{tabular}{l}
\textless smiles\textgreater[R1]C(=O)[R2]\textless/smiles\textgreater
\end{tabular} &
\begin{tabular}{l}
\textless smiles\textgreater[R]C=O\textless/smiles\textgreater
\end{tabular} &
\begin{tabular}{l}
\textless smiles\textgreater[R]C(=O)O\textless/smiles\textgreater
\end{tabular} &
\begin{tabular}{l}
\textless smiles\textgreater[R]OC([R])=O\textless/smiles\textgreater
\end{tabular} \\
\hline
\end{tabular}
\][/tex]
Thus, the structure diagram that completes the table for the ketone functional group is [tex]\([R1]C(=O)[R2]\)[/tex].
