The electronegativity difference between carbon and oxygen is 0.89 D, pretty large. Aromatic compound has a benzene ring substituted propyl crew for one of the vital hydrogen atoms which contains aromatic. The black portions of the bars are a property of the solid and are completely unaffected by the choice of solvent. Smaller alcohol molecules tend to be more soluble than larger alcohol molecules. As both these energies are less than the resonance energy of benzene, benzene is more stable than anthracene and phenanthrene. 1Butanol consists of a polar, hydrophilic hydroxyl residue and a nonpolar, hydrophobic hydrocarbon chain. Note: Here we see the structure of anthracene. The effect of the solvent and the . Naphthaline is quite flammable, so nowadays a lot of mothballs are made of the synthetic chemical pdichlorobenzene, which has a lower fire risk. naphthalene is a non polar substance so it will dissolve in non poalr solvent and camphor pon the other hand will dissolve in polar solvent.
