Polar and Non polar covalent bonds in lewis structures

[305339018]

Do we need to identify polar and non polar covalent bonds in lewis structures?

[Kevin Liu 1J]

I'm not too sure what you mean, but we are sometimes asked to indicate partial positive and negative charges, which is an indication of whether or not the bond is polar.

[Noah Canio 3C]

You don't necessarily have to define them as such, but understanding that some compounds are either polar or non-polar would help you understand the composition of a given compound. If they're polar, then they're represented with "dipole moments," as there's going to be a portion of the compound that holds on to electrons more tightly (the more electronegative atom) than the other part of the compound.

defining them is not very necessary but knowing what it means should be helpful.
