Mark the compound which possess ionic, covalent and coordinate bonds.

Answer: Option A

Ammonium chloride (NH₄) is generally considered as an ionic compound but this compound has three different types of bond. There is ionic bond between NH₄⁺ ion and Cl^- ion. There are N-H covalent bonds. The formation of NH₄⁺ from NH₃ is sometimes described as the formation of a coordinate bond between NH₃ and H⁺ , however once the bond is formed there is no difference between the four N-H bonds, NH₄⁺ has a tetrahedral structure.
