Question

if the dipole moments from from covalent bonds dont cancel, then the molecule will be ____

Answer 1

This site is used for learning, so to give a better understanding, here is  a walkthrough.

So let's create a question:

Can a molecule have a dipole moment if it has no polar covalent bonds?

Here's the answer to that question:

Even though a molecule contains only one element, it can have a persistent dipole moment. The most common example is ozone (trioxygen). It is curved and has a partial positive charge on the center oxygen atom (similar to sulfur dichloride).

Permanent dipole moments are caused by an unequal, directed charge distribution within a molecule, not by changes in electronegativity. Such charge distributions are frequently caused by so-called "polar covalent bonds," which occur between atoms with markedly varying electronegativity. However, they are not the sole explanation.

So using this information, try to answer this question on your own.
