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.
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.
For example many organic compounds are nonpolar molecules.
Br2 is a nonpolar covalent bond.
yes
polar
Within the molecule, the bonds are covalent bonds. Between water molecules, they're hydrogen bonds.
Yes, a CS2 molecules contains two double covalent bonds.
A strongest polar covalent bond cannot be defined as every such bonds contain ionic and covalent properties to a certain percentage.
The molecule is covalent, the N-F bonds are polar covalent.
This molecule contains polar covalent bonds.

The molecule is covalent, the N-F bonds are polar covalent.
Yes, a molecule can be nonpolar when it contains polar covalent bonds, because think about it. if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar.
It is a polar molecule and has polar bonds.
Yes a molecule can be nonpolar when it contains polar covalent bonds, because think about it.if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar
No, TNT is a molecule not a bond. Any covalent bond between atoms of different elements are polar to some extent, so yes, it contains many polar covalent bonds.
A molecule is not any kind of bond! Instead it has or contains bonds. The bonds in HCN are covalent but fairly strongly polar.
