Explain the significance of the hydrogen bond correct answers •Similar to ionic bond but weak •Polarity causes water molecules to form weak (hydrogen) bonds between water molecules •Although the hydrogen bond between molecules is only 5% as strong as the bonds between hydrogen and oxygen (covalent bonds), it accounts for many of water's important properties •The way we see water today is almost a gel because of the hydrogen bonds Special properties of water (hydrogen bond is behin...

Intermolecular forces and how they affect physical properties /purification techniques: dipole-dipole, electrostatic, hydrogen, ion, london, - Answer-*dipole-dipole*: polar covalent molecules such as aldehydes and ketones. positive and negative end. polar molecules must be close together for force to be significant. weaker than ion-dipole forces; increase with polarity of molecule. *electrostatic*: occur between charged species, cations and anions, and are responsible for very high MP and B...
