    Which type of bond is present in\[{{H}_{2}}S\]molecule?

    A)  Ionic bond

    B)  Covalent bond

    C)  Co-ordinate bond

    D)  All of the above

    Correct Answer: B

    Solution :

                     Electronic configuration of\[_{16}{{S}^{32}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{4}}\]. In the last orbit it has only six electrons. So, it requires 2 electrons to complete its octet. Therefore, it share 2 electrons with two hydrogen atom and forms 2 covalent bond with it.
