Questions & Step-by-Step Solutions

Which of the following has a molecular geometry that is not symmetrical?
  • Step 1: Understand what molecular geometry means. It refers to the 3D shape of a molecule.
  • Step 2: Learn about symmetry in molecular geometry. A symmetrical shape looks the same from different angles.
  • Step 3: Identify the molecule in question, which is NH3 (ammonia).
  • Step 4: Determine the shape of NH3. It has a trigonal pyramidal shape.
  • Step 5: Recognize that NH3 has a lone pair of electrons on the nitrogen atom, which affects its shape.
  • Step 6: Conclude that because of the lone pair, NH3 is not symmetrical.
