Question
Water is a covalently bonded substance.Which one of the following statements is true?More energy will be needed to overcome the intermolecular forces than the intramolecular forces in water.Less energy will be needed to overcome the intermolecular forces than the intramolecular forces in water.The same amount of energy will be needed to overcome the intermolecular forces and intramolecular forces in water.
Solution
Less energy will be needed to overcome the intermolecular forces than the intramolecular forces in water.
Here's why:
-
Intramolecular forces are the forces that hold atoms together within a molecule. They are much stronger than intermolecular forces, which are the forces of attraction between different molecules.
-
In water, the intramolecular forces are the covalent bonds between the hydrogen and oxygen atoms within each water molecule. These are very strong bonds and require a lot of energy to break.
-
The intermolecular forces in water are primarily hydrogen bonds between different water molecules. While these are relatively strong for intermolecular forces, they are still much weaker than the covalent bonds within each water molecule.
-
Therefore, it takes less energy to overcome the intermolecular forces (break the hydrogen bonds between different water molecules) than it does to overcome the intramolecular forces (break the covalent bonds within each water molecule).
