A. Do you expect polar or nonpolar liquids to form the roundest drops?

The polarity of a liquid is defined as the difference in electronegativity between the bonded atoms. The liquids based on the difference can be polar or nonpolar.

The polar molecules have higher chances to form the roundest drops.

A polar molecule such as water has an unequal distribution of electron density. The polarity of the water arises from the difference in the electron density of the bonded atoms.

The polarity of the water molecule, these molecules are pilled in the middle of the volume, such that the drop of the water will be rounded.

The polarity or the difference in the charges of hydrogen and oxygen atoms will attract the atoms leading to the formation of round beads, whereas such as oil, a non-polar compound does not form beads due to lack of electronegativity.
