    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\[NaCl,\text{ }CsCl\]and\[LiF\]are ionic, while \[{{H}_{2}}O\]forms a covalent bond.
