Question

Discuss in brief about the properties of coordinate covalent compounds. [3 Marks]

Answer 1

Some of the properties of coordinate compounds are as follows:

(a) Physical state – These compounds exist as gases, liquids or solids. [0.5 Marks]

(b) Electrical conductivity – Like covalent compounds, coordinate compounds also do not contain charged particles (ions), so they are bad conductors of electricity. [0.5 Marks]

(c) Melting point and boiling point – These compounds have melting and boiling points higher than those of purely covalent compounds but lower than those of purely ionic compounds. [1 Mark]

(d) Solubility – Insoluble in polar solvents like water but are soluble in non-polar solvents like benzene, CCl₄, and toluene. [0.5 Marks]

(e) Reactions – Coordinate covalent compounds undergo molecular reactions which are slow. [0.5 Marks]
