### Aromaticity Classification of Molecules/IonsBelow are several molecules and ions. You are required to classify each as aromatic, antiaromatic, or nonaromatic, assuming all structures are planar.#### Structures to Identify:1. **First Row:** - First Structure: A fused ring system containing a five-membered ring with an oxygen atom. - Second Structure: A bicyclic compound composed of two fused benzene rings (napthalene). - Third Structure: A five-membered ring with a positive charge (tropylium ion). - Fourth Structure: A seven-membered ring with alternating single and double bonds, including a positive charge.2. **Second Row:** - First Structure: A three-ring fused system with the central ring being a six-membered ring. - Second Structure: A four-membered ring with two positive charges. - Third Structure: A bicyclic compound composed of two eight-membered rings. - Fourth Structure: A benzene ring with a side chain consisting of an ethylene group.3. **Third Row:** - First Structure: A polycyclic aromatic hydrocarbon with three fused benzene rings in a linear arrangement. - Second Structure: A six-membered ring with one sulfur atom in it (thiophene). - Third Structure: A six-membered ring with one nitrogen atom in it (pyridine). - Fourth Structure: A large 16-membered aromatic ring.### Analysis Explanation:- **Aromatic compounds** follow the Huckel’s Rule where the number of π-electrons is given by 4n+2, and the ring is planar and fully conjugated.- **Antiaromatic compounds** have 4n π-electrons, are planar, and fully conjugated.- **Nonaromatic compounds** do not follow the criteria for aromatic or antiaromatic compounds, often being non-planar or not fully conjugated.### Detailed Graph Description:Each molecular diagram is depicted in a standard chemical structure format, showing atoms (such as carbon represented by vertices and other elements like oxygen and nitrogen explicitly written) and the bonds between them as lines. Positive charges are indicated by "+" and cyclic structures are represented with geometric shapes like hexagons, pentagons, etc.This collection of diagrams serves as a reference for understanding and classifying the types of aromaticity in different organic molecules and ions.
