Question: What is the primary factor that determines the polarity of a molecule?

Options:

Correct Answer: Shape of the molecule

Solution:

The shape of the molecule determines how bond dipoles add up, affecting overall polarity.

What is the primary factor that determines the polarity of a molecule?

Step 1: Understand that molecules are made of atoms connected by bonds.
Step 2: Recognize that bonds can have a property called 'dipole moment', which indicates how polar a bond is.
Step 3: Know that a dipole moment occurs when there is an uneven distribution of electrical charge in a bond.
Step 4: Learn that the shape of the molecule affects how these dipole moments from different bonds combine.
Step 5: Realize that if the dipole moments cancel each other out, the molecule is nonpolar.
Step 6: If the dipole moments do not cancel out, the molecule is polar.
