Towards the end of the year, the weather in Seville starts to become slightly milder. In October, the sun shines for at least 7 hours per day but brace yourself for rain as there are on average 6 days of rainfall during the month.
When a molecule has no dipole moment, like CO2, then it is nonpolar. When a molecule has a dipole moment like water, then it is polar. This polarity business is very important. Polar molecules are like little magnets, with a positive end and a negative end, and they interact with each other through magnetic attractions.
Hydrogen bonding is a strong dipole-dipole attraction that forms between molecules in which hydrogen is bonded to one of the electronegative elements nitrogen, oxygen and fluo â¦ rine. (dipole-dipole bonds are bonds between dipoles-a molecule that has two oppositely charged poles or ends).luorine, oxygen, nitrogen and carbon only. The first three are very electronegative elements bond with hydrogen to form hydrogen bonding. Carbon can also participate in hyd â¦ rogen bonding, especially when the carbon atom is bound to several electronegative atoms, as is the case in fluoroform, CHF3.
