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