What are examples of nonpolar molecules?

Answer 1

There are many non-polar substances. Some are rigorously and completely non-polar (in others, they have zero permanent dipole moment). Others are not perfectly non-polar, but are generally called non-polar compounds because they lack any significant polarity. Completely non-polar: Nitrogen gas (N2), methane gas (CH4), oxygen gas (O2), chlorine gas (Cl2) (and homogeneous diatomic molecules such Br2, I2, and F2), acetylene (C2H2), carbon tetrachloride (CCl4). Note that these are all perfectly symmetrical and this is why they are non-polar. The dipole moments of any polar bonds is completely canceled out by equal and opposite dipole moments from the other bonds.

Mostly non-polar: All basic hydrocarbons (such as propane, butane, pentane, hexane, cyclohexane, octane and others), oils (such as vegetable oils), fats and greases, gasoline, diethyl ether, and others.

Answer 2

Non-polar molecules have a net dipole moment of 0. Although non-polar molecules may contain polar bonds, they are arranged so that the dipoles cancel each other out.

Examples of non-polar molecules include:

carbon dioxide, CO2

carbon tetrachloride, CCl4

Answer 3

In order to be non-polar, a molecule must have an equal distribution of valence electrons. Also, the electronegativitys of the outer atoms must be balanced.

For instance, water is polar because the oxygen has two sets of lone pair electrons and two sets of bonded electrons each connected to a hydrogen atom. The lone pais make that side of the molecule more negative, and therefore make the other side more positive. This is called a dipole. A dipole is not an actual charge. It is merely the asymmetry of the electron distribution causing one side to have more electrons than the other.

So non-polar liquids involve molecules with perfectly symmetrical Lewis Dot structures. Examples would be methane, ethane, propane, etc. Check out the website below for the Lewis structures of these molecules.

Other examples of non-polar molecules would be all the diatomics molecules. Even though some of them have lone pairs, all the lone pairs are even on both sides.

The most common and cheap example of a non-polar liquid is vegetable oil. But all oils are non-polar. Gasoline is also non-polar, but the flammability should be considered when working with it in a lab.

Answer 4

Molecules may be polar or non-polar depending on their composition. An example of a polar molecule is an acid like acetic acid. An example of a non-polar molecule is a pure hydrocarbon like pentane that does not contain any polar or ionizable atoms.

Answer 5

Most hydrocarbons are nonpolar. Such as CH4 or gasoline.

Answer 6

One example of a nonpolar molecule is O2, or any other element bonded to itself. Another example would be a molecule made of hydrogen and carbon, such as methane, CH4.

Answer 7

Co2, CFl4, and pretty much any hydrocarbon eg. methane or hexane

Answer 8

CCl4-Carbon Tetrachloride

CO2-Carbon Dioxide
