The correct options are
B They dissolve in organic solvents.
C They have high melting point than pure covalent compounds.
Properties of coordinate compounds are as follows:
- They do not give individual ions in water and are poor conductors of electricity.
- They are sparingly soluble in water and dissolve in organic solvents.
- They possess melting and boiling points higher than those of purely covalent compounds, but lower than that of ionic compounds.
- They are semi-polar in nature.
