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.

Identify the incorrect statement and correct them.
- Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity.
- Ionic bond is a weak bond when compared to Hydrogen bond.
- Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms.
- Loss of electrons is called Oxidation and gain of electron is called Reduction.
- The electrons which are not involved in bonding are called valence electrons.
