    The hybridization of atomic orbitals of nitrogen in \[NO_{2}^{+},\]\[NO_{2}^{-}\]and \[NH_{4}^{+}\] are

    A) \[s{{p}^{2}},\] \[s{{p}^{3}}\] and \[s{{p}^{2}}\] respectively

    B) \[sp,\] \[s{{p}^{2}}\] and \[s{{p}^{3}}\] respectively

    C) \[s{{p}^{2}},\] \[sp\] and \[s{{p}^{3}}\] respectively

    D) \[s{{p}^{2}},\] \[s{{p}^{3}}\] and \[sp\] respectively

    Correct Answer: B

    Solution :

    [b] \[NO_{2}^{+}=1/2[5+0+0-1]=2\,sp;\] \[NO_{2}^{-}=1/2[5+0+0-1]=3\,s{{p}^{2}};\] \[NO_{4}^{+}=1/2[5+4+0-1]=4\,s{{p}^{3}}\]
