Development of the Modern Freezer. Bacteria are usually the cause of food decay, but they can't grow as well or at all in freezing temperatures, which are at 32 degrees Fahrenheit (0 degrees Celsius) or lower.
HF- polar molecule: dipole-dipole forces. There are also dispersion forces and H bond between HF. BF3- nonpolar: dispersion forces. Ar- Dispersion forces between Ar atoms.
1 hydrofluoric acid - HF - Hydrofluoric acid forms what is called a symmetric hydrogen bond, which is stronger than the regular hydrogen bond. This type of bond also forms in formic acid. 2  proteins - Hydrogen bonds result in protein folding, which helps the molecule maintain stability and assume a functional configuration.
