What feature makes a polar molecule?

Answer 1

i love you :)

dude really? im looking for a answer to this question "i love you :)" doesn't really answer it. like seriously if yer gonna post a "answer" can u atleast answer the actual question? k thanks(:

Answer 2

A polar molecule has an uneven distribution of electrons, causing one end of the molecule to have a slightly positive charge and the other end a slightly negative charge. This results in a molecule with a permanent dipole moment.

Answer 3

First, it is best to bring up the four types of elemental bonding. The types are respectively polar bonds, nonpolar bonds, ionic bonds, and hydrogen bonds. They have been listed in respect to the general strength of the bond.

Now, we will not divulge into the types of ionic nor hydrogen bonding because that is not related to the question.


Polar and nonpolar bonding are the two principle bonding methods between nonmetal elements. These two types involve electron sharing between the elements bonded.


The significance that defines the boundaries of polar and nonpolar bonds are whether the electrons are shared "equally." The reason electrons are shared is so an atom can achieve an electron configuration of that of a noble gas whose electron configuration is exceptionally stable.


Although at any one time an electron is either in orbit around one of the bonded atoms, the electron spends an approximately equal time in orbit around all atoms in a nonpolar bond. This usually occurs when the elements bonded have a similar electron affinity (ability to take on another electron).


In short, many of the nonpolar bonds occur between atoms of the same element. however, this does not mean that a nonpolar bond does not occur between different elements. For example, triglycerides (also known as a fatty acid) has the empirical chemical formula of CH3 creates a relatively nonpolar bond. This is the reason it does not dissolve readily in water which is polar.


In a polar bond, the electrons are shared unequally. This usually occurs between nonmetal atoms that differ significantly in electron affinity. This means that the electron shared would spend a theoretically greater period of time in orbit around the more electronegative atom. This creates a region (where the electron is around) that is slightly negative, and it create a region (where the electron is not much around) that is slightly positive. A well known example is that of water. A water molecule (H2O) is a polar molecule. The oxygen has a higher electron affinity than hydrogen (and also more protons and therefore a greater positive charge). This pulls the electrons closer to the oxygen nucleus and gives the oxygen a smaller negative charge. The hydrogen spends less time with the electrons and now has a region that is slightly positive.


Hope this helps.
