    The ionic bond is absent in                  

    A)  \[NaCl\]         

    B)  \[CsCl\]

    C)  \[LiF\]          

    D)  \[{{H}_{2}}O\]

    Correct Answer: D

    Solution :

    Ionic bond is a type of chemical bond based on electrostatic forces between two oppositely charged ions. In ionic bond formation a metal donates an electron, due to a low electronegativity to form a positive ion or a cataion. Often ionic bonds are formed between metals and non-metals. Hence, bond between \[NaCl,\]\[CsCl\] and \[LiF\] are ionic, while \[{{H}_{2}}O\] forms a covalent bond.
