Questions & Step-by-Step Solutions

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.
