Question

which of the following does not affect the polarity of a molecule?
the geometric shape of the molecule
the electronegativity difference between the atoms
the state of the substance
the nature of the atoms in the bond

Explanation:

Molecular polarity depends on bond polarity (from electronegativity difference/nature of bonded atoms) and molecular geometry (which determines if bond dipoles cancel). The state of the substance (solid/liquid/gas) is a physical state change that does not alter the molecule’s structure or bond properties, so it does not affect polarity.

Answer:

the state of the substance
