What is the difference between a nonpolar covalent bond and a polar covalent bond?

Oleic acid is only composed of C/H/O - and is Organic. Polar or Nonpolar is a bit tough. For big molecules like this, it is easier to think in terms...

On Mohs scale, isn't diamond assigned a $10$ on the basis of hardness? Halite is almost a purely ionic material.

The modern covalent bond is conceived to be a region of high electron between 2 positively charged atomic nuclei such that nucleus/nucleus repulsion is negated, and a net attractive force...

The electronegativity of the atoms involved in a covalent bond determines which will have more pull on the electrons shared between them. Because all atoms have different electronegativities, the only...

Both bonds result in forming of differentiating properties and structures. Atoms react in order to achieve stability. However, covalent bonds have a unique property that ionic bonds do not...

Something worth knowing about deciding between nonpolar and polar is that only two of the same element can form an ideally nonpolar bond. With this in mind, the $"Br"-"Br"$...

Where the $delta$ symbol denotes a little bit of (or partial) positive or negative charge. Dipoles are drawn from positive to negative. The overall dipole moment is the vector sum...

$"......and their VECTOR sum gives no resultant dipole."$ $CO_2$ is a linear molecule, and the $/_"O"-"C"-"O"$ is $180^@$. Dipoles are vector quantities; they have magnitide and direction. While there is...

Molecular polarity is conceived to result from the VECTOR sum of the individual bond dipoles. For a molecule such as $CX_4$ $("X = halide")$, the individual bond dipoles are...

If you have a substance with nonpolar molecules , the only that exist are London-Dispersion forces, which are very weak. However, if you have a substance with polar molecules, then...
