Question
Low melting point and low solubility in water are general properties of ___________ type of compound.
- Chemical
- Covalent
- Ionic
- Physical
Hint:
Covalent bonds are formed by sharing of electrons between atoms.
The correct answer is: Covalent
- Covalent bonds require less amount of energy to break hence the compounds show low melting point.
- Electrovalent compounds dissolve in polar solvent like water because the forces of attraction between positive and negative charges become weak in water. But since covalent compound are made up of molecules, they do not ionize in water and hence do not dissolve in water.
