Explanation:
Methanol is a covalent compound with the chemical formula CH3OH. It consists of a carbon atom bonded to three hydrogen atoms and one oxygen atom. The oxygen atom is also bonded to the carbon atom through a covalent bond.
Methanol is soluble in water due to the presence of hydrogen bonding between methanol and water molecules.
Hydrogen Bonding:
Hydrogen bonding occurs when a hydrogen atom is bonded to an electronegative atom (such as oxygen or nitrogen) and is attracted to another electronegative atom nearby. In water molecules, the oxygen atom is more electronegative than the hydrogen atoms, giving rise to a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms.
In methanol, the oxygen atom is also electronegative, and the hydrogen atom bonded to it is partially positive. This allows the oxygen atom in methanol to form hydrogen bonds with the oxygen and hydrogen atoms in water molecules. The partial positive charge on the hydrogen atoms in water molecules can interact with the partial negative charge on the oxygen atom in methanol, and vice versa, forming hydrogen bonds.
Benefits of hydrogen bonding:
The presence of hydrogen bonding between methanol and water molecules allows them to interact and mix together. This leads to the dissolution of methanol in water.
Hydrogen bonding is a relatively strong intermolecular force, so it overcomes the weaker van der Waals forces between methanol molecules. Van der Waals forces are attractive forces between molecules, but they are weaker than hydrogen bonding. Therefore, the hydrogen bonding between methanol and water molecules is the primary reason for the solubility of methanol in water.
Conclusion:
In conclusion, methanol is soluble in water due to the presence of hydrogen bonding between methanol and water molecules. This allows them to mix together and form a homogeneous solution.
