Comparison of Polar Molecules: Water and Aldehyde

Flashcards summarizing key concepts from the lecture on comparing the properties of water and aldehyde as polar molecules.

Which liquid has a higher boiling point, water or aldehyde?

Water has a higher boiling point due to stronger intramolecular forces.

What determines the volatility of a liquid?

Volatility is determined by the strength of the bonds; weaker bonds allow easier gas formation.

Which liquid is more volatile, water or aldehyde?

Aldehyde is more volatile because it has weaker bonds.

Which liquid has a higher surface tension, water or aldehyde?

Water has a higher surface tension due to stronger intermolecular forces.

What is the significance of NaCl in comparison to water?

NaCl is more soluble in water, affecting various chemical properties.

What substance has a lower melting point, solid water or solid aldehyde?

Solid aldehyde has a lower melting point compared to solid water.
