NO
HCl, because the difference between the electronegativities of the two atoms has the largest value of any of the four formulas given.
The most common examples of totally nonpolar molecules are the elements with diatomic molecules, such as N2, O2, F2, etc.
Mainly a non polar covalent bond is between atoms of same element.eg:-O2,H2,N2 etc. Though the bonds are polar molecules can be non polar. Eg-CO2,CH4
2 of the same atoms bonding to each other. Their polaraties cancel each other out which makes them non-polar Cl2 H2 O2 Statement above is good but incomplete. There are a total of 7 non-polar diatomic molecules. H2 O2 N2 F2 Cl2 Br2 I2 If you are taking chemistry this must be memorized.
Any of the diatomic molecules like H2 gas, O2 gas, N2 gas, etc.
O2, N2, Cl2, I2, as well as F2, Br2, and H2 are all diatomic elements.
CO

F2 is non polar. Diatomic molecules composed of two of the same elements are always non-polar. Examples are O2 H2 Cl2 and N2.Nonpolar. No element on its own is polar.

Any of the diatomic molecules like H2 gas, O2 gas, N2 gas, etc.
O2, N2, Cl2, I2, as well as F2, Br2, and H2 are all diatomic elements.
A N2 molecule consists of two atoms of nitrogen, and an O2 molecule consists of two atoms of oxygen.
generally looking at the structures of the molecules we can say wether that molecules is polar or non polar. generally linear and square planer molecules are non polar. further more diatomic molecules like (N2,O2,H2,I2,F2,Cl2,Br2) are non polar. all nobel gases are non polar.Yes, polar bond can give rise to a polar molecule, depending on the molecular shape, causing different types of changes.
'Air' is a mixture of covalent molecules such as N2 O2 and CO2
O2
Elements prefer to live in their natural forms.N2 and O2 are more stable than NO.Added:Air is a mixture of N2 and O2 molecules, where NO is a compound, chemically formed by reaction: N2 + O2 --> 2 NO. This reaction does not take place at normal conditions as in the air around us.
