is oxygen a polar molecule?

Question

give reason for your answer

Answer 1

no, because an oxygen molecule (O2) would have an equal electronegative attraction because it is 2 of the same atom and nothing else.

Answer 2

I'm afraid I have to disagree with some of your correspondents.

The oxygen molecule is indeed polar, simply stated the reason is as follows. The chemical bonding in the molecule allows for 2 covalent bonds to be formed between the oxygen atoms via sp2 hybridisation. This leaves an isolated pair of electrons is a p orbital. This lone-pair of electrons explains the eletronegativity of oxygen (if a material is electropositive or electronegative then by definition there must be a degree of polarity); it also explains why liquid oxygen is magnetic.

Answer 3

Oxygen is not a polar molecule. The polarity of a molecule is based upon the bonding structure, and the electronegativity differences between the bonded atoms.

In this case O2 consists of only two atoms of oxygen and therefore the only bonding structure possible is linear. So draw a linear bond of two atoms and then draw arrows to portray the relative electronegativity. (Think about force diagrams in physics.) Since both atoms are oxygen they have the same electronegativity. Therefore the two arrows will be of equal length but opposite directions. They will cancel each other out to create a non-polar molecule.

This is exactly like balancing forces in physics, and gets more complex with more complex molecules. :-)

Answer 4

No it is not. Firstly, polar means an uneven distribution of charge within a molecule i.e. the presence of a dipole.

A dipole is created in a heteroatomic molecule i.e. a molecule with atoms that have different electronegativities. This is because the bonding electrons are found closer toward the more electronegative atom, making that atom slightly negative and
hence making the molecule polar.

A molecule consisting of only one type of atom e.g. O2 cannot have a dipole as the charge is distributed evenly between the two atoms

Answer 5

Liquid oxygen is blue, and the substance is paramagnetic. This would normally indicate the existence of unpaired electrons, which the normal O=O bonding diagram does not explain.
The true situation is that oxygen is more likely to be .O-O., with an unpaired electron on each O atom. This goes a long way in explaining the high reactivity of molecular oxygen. Even these unpaired electrons would arrange themselves symmetrically, on average, so I would have to say that oxygen, although paramagnetic, is non-polar.

Answer 6

No.

Oxygen as O2 is linear molecule with a double bond 0=0

This is too symmetric to be polar.

Oxygen as ozone O3 is an equilateral triangle with an oxygen at each corner, and again is too symmetrical to be polar.

Answer 7

No to be polar you require two different atoms so water is polar but not oxygen.

Answer 8

No. Any molecule comprised of two of the same element is non polar, ex: H2, O2, N2, Cl2, F2

Answer 9

Depends!! don't just come on here for the answer, study vsepr shaping to find out the answers~!

O2 is not polar! but Ozone (O3) might be! check it out!

Good Luck!

Answer 10

it has electronegativity, but it will depend on what its bonbing with.
