Which phenomenon predominantly limits conductivity in molecular wires assembled from aromatic molecules at room temperature?

💡 Explanation

When temperature increases, increased thermal vibrations alter the conformation of the aromatic molecules, disrupting the vital pi-orbital overlap which facilitates electron transport, limiting conductivity. Therefore, disrupted orbital overlap limits conductivity, rather than tunneling, Coulomb blockade, or electromigration, which require different temperature or voltage conditions.
