In which of the following molecular shape `d_(z^(2))` orbital must not be involved in bonding ?

Draw the shape of d_(z^(2)) orbital .

In which of the following d_(z^(2)) orbital is participating in hybridisation ?

Which of the following d-orbitals has donut shape ?

Which of the following orbital of central atom is not involved in bonding in XeO_(3) F_(2) molecule :-

Molecular orbital theory as developed by Hund and Mulliken concerns with the formation of molecular orbitals formed by linear combination of atomic orbitals. The electrons are present in these molecular orbitals. The molecular orbitals are filled. The molecular orbital configuration helps us to calculate bond order which gives information about the number of bonds present between atoms. The bond order is related to bond length and bond strength. Which of the following will have maximum number of electrons in antibonding MOs?

Which atomic orbital is always involved in sigma bonding only ?
