question 13 (1 point)
which of the following does not affect the polarity of a molecule?
the nature of the atoms in the bond
the geometric shape of the molecule
the electronegativity difference between the atoms
the state of the substance
question 14 (1 point)
which of the following is an example of an intermolecular force?
sigma bond
covalent bond
pi bond
dipole - dipole force

Explanation:

• Question 13:
• The polarity of a molecule depends on the nature of atoms (affects electronegativity), the geometric shape (determines if dipoles cancel), and electronegativity difference (creates bond polarity). The state of the substance (solid, liquid, gas) is a physical property and has no impact on molecular polarity.
• Question 14:
• Sigma bonds, covalent bonds, and pi bonds are intramolecular forces (within a molecule). Dipole - dipole force is an intermolecular force (between molecules).

Answer:

• Question 13: the state of the substance
• Question 14: dipole - dipole force
