Answer: C. Stalin and Hitler signed ….
Explanation: i just took the test.
According to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.
<h3>What are dipole-dipole attractions?</h3>
It is observed between a positive dipole of a polar molecule with the negative dipole of another, the atom with the highest electronegativity attracts electrons towards itself, forming a negative dipole around it.
In polar covalent bonds, the atom with the least electronegativity, the dipole formed has a positive charge, since it partially gives up its electrons.
Therefore, we can conclude that according to the research, the statement "Linear molecules must be nonpolar, thus linear molecules cannot participate in dipole-dipole attraction" is true.
