Work Step by Step
Based on the provided electrostatic potential diagrams, the correct labeling and explanations are as follows:
a. This diagram represents the molecule H2O (water).
Explanation: The electrostatic potential diagram shows a molecule with a bent or angular shape, which is characteristic of the water (H2O) molecule. The oxygen atom, being more electronegative than the hydrogen atoms, attracts the electrons more strongly, resulting in a partial negative charge (blue region) around the oxygen and partial positive charges (red regions) around the hydrogen atoms. This charge distribution and the resulting molecular shape are typical of the water molecule.
b. This diagram represents the molecule NH3 (ammonia).
Explanation: The electrostatic potential diagram shows a molecule with a pyramidal or trigonal pyramidal shape, which is characteristic of the ammonia (NH3) molecule. The nitrogen atom, being more electronegative than the hydrogen atoms, attracts the electrons more strongly, resulting in a partial negative charge (blue region) around the nitrogen and partial positive charges (red regions) around the hydrogen atoms. This charge distribution and the resulting molecular shape are typical of the ammonia molecule.
c. The tetrahedral diagram represent CH4.
