Aromatic Compounds

Aromatic organic compound or aromatic system is an important class of hydrocarbons under the branch of organic chemistry. Aromatic compounds are also called arenas. The definition of aromatic organic compounds can be stated as a class of organic compounds with a planar cyclic ring of atoms bonded through alternated single and double bonds. Due to these alternating bonds, a peculiar feature termed as ‘resonance’, that is, delocalization of pi electrons or the electrons is shared within the atoms of the ring which are present in the aromatic compounds. The word ‘aromatic’ includes a Greek word ‘aroma’ which means smell, indicating that they were named as such due to the sweet odor they produce. Many well-known flavors such as vanilla, cinnamon, and few scents from flowers are extracted from aromatic compounds. Benzene with chemical formula C6H6 is a very common aromatic compound that contains six atoms of carbon held in the cyclic ring of alternate double bonds. It is also to be noted that not all aromatic compounds contain benzene ring. This can be explained by Huckel’s rule.

**Mechanism for the Reaction**

**Objective:** Write a mechanism for the following reaction. You *MUST* use curved arrows to represent electron movement to get full credit. Show the transition state of the reaction.

### Reaction Scheme

\[
\begin{array}{cccc}
&& \overset{\text{CH}_3\text{CH}_2\text{S}^- \cdot \text{Na}^+}{\longrightarrow} & \\
& \text{S}-\text{CH}_2\text{CH}_3 & \\
& \downarrow \text{Transition State} & & \text{S}-\text{CH}_2\text{CH}_3 \\
\end{array}
\]

### Explanation

1. **Curved Arrows:** Use curved arrows to indicate the movement of electrons during each step of the reaction mechanism.
2. **Electron Movement:** Represent the nucleophilic attack by the CH₃CH₂S⁻ ion on the electrophile.
3. **Transition State:** Show the structure of the transition state formed during the reaction.

> Note: Ensure all arrows are clearly drawn to show the movement of electron pairs.

Penicillins and other β-lactam antibiotics typically develop a resistance to bacteria due to bacterial synthesis of β-lactamase enzymes. Tazobactam, however, is able to inhibit the activity of the β-lactamase by trapping it, thereby preventing resistance from developing.
