What does it mean to be polar vs nonpolar?
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
What does it mean to become polar?
By definition, polarity is basically the status of having "poles." In a molecule, this means that the molecule has poles of positive and negative charge—also known as a separation of charge. Let's take a look at a classic example of polarity: the water molecule.
Is I and C polar or nonpolar?
Hydrogen and carbon have similar electronegativity values, so the C—H bond is not normally considered a polar covalent bond. Thus ethane, ethylene, and acetylene have nonpolar covalent bonds, and the compounds are nonpolar. ... Polar Covalent Bonds.

Which molecule is polar?
Polar molecules are those that possess regions of positive and negative charge. Water is an example of a polar material. The type of bonds it has, when coupled with its shape, gives one end of the molecule a slight positive charge (the hydrogen end) and the other a slight negative charge (the oxygen end).
