What two conditions necessary for molecules to be polar? Her's my answer pls check.
First, at least one covalent bond in the molecule has to be a polar covalent bond. For a bond to be polar, there must be a difference in the electronegativities of the two atoms that are bonded together. The second condition is that the molecule cannot be perfectly symmetrical.
