Which of the following has a pyramidal shape?

Which of the following has a pyramidal shape?

Step 1: Identify the molecule in question, which is NH3 (ammonia).
Step 2: Determine the number of bonding pairs of electrons in NH3. There are three hydrogen atoms bonded to the nitrogen atom.
Step 3: Identify the number of lone pairs of electrons on the nitrogen atom. NH3 has one lone pair.
Step 4: Understand that the shape of a molecule is determined by the arrangement of bonding pairs and lone pairs of electrons.
Step 5: Recognize that NH3 has three bonding pairs and one lone pair, which leads to a trigonal pyramidal shape.
Step 6: Conclude that NH3 has a pyramidal shape due to the presence of the lone pair pushing down on the bonding pairs.
