Which molecule contains non polar covalent bonds?

Answer 1

Nonpolar molecules are of two types. Molecules whose atoms have equal or nearly equal electronegativities have zero or very small dipole moments. A second type of nonpolar molecule has polar bonds, but the molecular geometry is symmetrical allowing the bond dipoles to cancel each other.

Answer 2

Any molecule where the two atoms bonded together have the same electronegativity - e.g. an element such as O2. Some molecules can have polar bonds but be non-polar overall if the polarity of the bonds 'cancel out', e.g. CO2, CCl4, NH4+ This happens if the bonds are pointing in opposing directions - draw out a diagram of CO2 which has two polar double bonds to see this. Remember to consider the shape of the molecules (including lone electron pairs) when looking at the polarity of the whole molecule.

Answer 3

For example many organic compounds are nonpolar molecules.

Answer 4

Br2 is a nonpolar covalent bond.

Answer 5

yes
