The structure of 4 - Nitroaniline consists of a benzene ring, which is a six - membered aromatic hydrocarbon ring with alternating single and double bonds.The structure of 4-nitroaniline is composed of a benzene, which is an aromatic hydrocarbon ring of six members with alternate single and double bonds. Attached to the benzene ring at the para position (opposite sides of the ring) are two functional groups.Two functional groups are attached to the benzene at the para positions (opposite sides). One is an amino group (-NH2) and the other is a nitro group (-NO2).The amino group (NH2) is one, and the nitro group is another.

The benzene ring in 4 - Nitroaniline provides the molecule with aromaticity.The aromaticity of the molecule is due to the benzene ring. Aromatic compounds are known for their stability due to the delocalization of p - electrons within the ring.Aromatic compounds are known to be stable due to the delocalization p-electrons within the ring.

The amino group (-NH2) is an electron - donating group.The amino group (NH2) is an elecron-donating group. It has a lone pair of electrons on the nitrogen atom that can be involved in resonance with the benzene ring.It has a pair of electrons that are lone on the nitrogen atom and can be involved in resonance. Through resonance, the lone pair of electrons on the nitrogen atom can be delocalized into the benzene ring, increasing the electron density of the ring at the ortho and para positions.The lone electron pair on the nitrogen atom is delocalized to the benzene rings through resonance. This increases the electron density in the ring's ortho and para positions.

On the other hand, the nitro group (-NO2) is a strong electron - withdrawing group.The nitro group (NO2), on the other hand is a strong group that withdraws electrons. The nitrogen atom in the nitro group is double - bonded to two oxygen atoms, and the high electronegativity of oxygen causes a withdrawal of electron density from the benzene ring.The nitrogen atom of the nitro group has a double-bond with two oxygen atoms. The high electronegativity oxygen causes the benzene to lose electron density. The nitro group also participates in resonance, but in a way that reduces the electron density of the benzene ring.The nitro group is also involved in resonance but in a manner that reduces the density of electrons in the benzene rings.

The intermolecular forces in 4 - Nitroaniline are influenced by the polar nature of the amino and nitro groups.The polarity of the amino and nitrogen groups influences the intermolecular force in 4 -nitroaniline. The amino group can form hydrogen bonds with other molecules, both through the lone pair of electrons on the nitrogen and the hydrogen atoms attached to the nitrogen.The amino group is able to form hydrogen bonds with molecules both by the lone electron pair on the nitrogen as well as the hydrogen atoms that are attached to the nitrogen. The nitro group, due to its polar nature, also contributes to dipole - dipole interactions.Due to its polarity, the nitro group also contributes to interactions between dipoles. These intermolecular forces hold the molecules together in the solid state, resulting in a relatively high melting point.These intermolecular interactions hold the molecules together at the solid state. This results in a melting point that is relatively high.

In terms of chemical reactivity, the electron - donating and electron - withdrawing effects of the functional groups on the benzene ring determine the sites where substitution reactions are likely to occur.The sites of substitution reactions that are most likely to occur are determined by the electron-donating and electron-withdrawing effects of functional groups on benzene rings. The increased electron density at the ortho positions relative to the amino group (due to resonance) makes these positions more nucleophilic.The resonance effect increases the electron density in the ortho positions relative the amino group, making these positions more nucleophilic. However, the strong electron - withdrawing effect of the nitro group can also influence the reactivity.The strong electron-withdrawing effect of nitro groups can also affect the reactivity. For instance, in electrophilic aromatic substitution reactions, the incoming electrophile will be directed to the positions that are less deactivated by the nitro group and more activated by the amino group.In electrophilic aromatic substitute reactions, for example, the incoming electron will be directed towards the positions where the nitro group is less deactivated and the amino group more activated.
