46. Mark the compound which possess ionic, covalent and coordinate bonds. A.NH4Cl B.SO3 C.SO2 D.H2O
Answer: Option A Solution: 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.
