We have to determine why hydrazine (NH2NH2), hydrogen peroxide (HOOH), and water (H2O) all have exceptionally high surface tensions in comparison with other substances of comparable molecular weights.
Surface tension is the tendency of a liquid to shrink into the minimum possible surface area.
Surface tension increases with the strength of intermolecular forces present among the molecules.
Polar liquids have a higher surface tension than nonpolar liquids.
Hydrazine (NH2NH2 ), hydrogen peroxide (HOOH), and water (H2O) all have exceptionally high surface tensions in comparison with other substances of comparable molecular weights.
What structural property do these substances have in common, and how might that account for the high surface tensions?
