प्रश्न
Discuss in brief about the properties of coordinate covalent compounds.
Advertisements
उत्तर
- Physical state – These compounds exist as gases, liquids or solids.
- Electrical conductivity – Like covalent compounds, coordinate compounds also do not contain charged particles (ions), so they are bad conductors of electricity.
- Melting point – These compounds have melting and boiling points higher than those of purely covalent compounds but lower than those of purely Ionic compounds.
- Solubility – Insoluble in polar solvents like water but are soluble in non-polar solvents like benzene, CCl4, and toluene.
- Reactions – Coordinate covalent compounds undergo molecular reactions which are
slow.
