  • question_answer \[\text{Xe}{{\operatorname{O}}_{4}}\] molecule is tetrahedral having:     JEE Main  Online Paper (Held On 22 April 2013)

    A)  Two \[p\pi -d\pi \] bonds

    B)  One \[p\pi -d\pi \] bond

    C)  Four \[p\pi -d\pi \] bonds

    D)  Three \[p\pi -d\pi \] bonds

    Correct Answer: C

    Solution :

     Xenon undergo sp3 hybridization. * In the fourth excited state xenon atom, has 8 unpaired electrons   One s and three p orbital undergo \[s{{p}^{3}}\] hybridization. Four \[s{{p}^{3}}\] hybrid orbitals form four \[\sigma \] bonds with oxygen atoms. They are \[\sigma s{{p}^{3}}-p.\]Four \[p\pi -d\pi \]bonds are also formed with oxygen atoms by the unpaired electrons.
