Webbför 2 dagar sedan · Nitrated polycyclic aromatic hydrocarbons (NPAHs) are a kind of polycyclic aromatic hydrocarbon (PAH) derivatives substituted by nitro group with semi-volatility, high hydrophobicity, and environmental persistence ( Bandowe and Meusel, 2024; Yadav and Devi, 2024 ). WebbAntiaromaticity is a chemical property of a cyclic molecule with a π electron system that has higher energy, i.e., it is less stable due to the presence of 4n delocalised (π or lone pair) electrons in it, as opposed to aromaticity.Unlike aromatic compounds, which follow Hückel's rule ([4n+2] π electrons) and are highly stable, antiaromatic compounds are …
