What is the valence molecular orbital configuration accordin

What is the valence molecular orbital configuration (according to MO theory) of homonuclear diatomic species where the atoms have an atomic number greater than seven? (Note that here we are distinguishing deg orbitals from each other where the two 2ps are shown as ll2pz and 2py. enerate Choose one: How many electrons are there in the antibonding orbitals of the following N2: C22+: Br22+ SUBMIT ANSWE

Solution

For atomic number greater than 7 electrons are filled in sequence of orbitals according to option A.

Sigma bonding 2p is filled first tha bonding 2p orbitals.So, the correct option is A.

N2^+ will have total 13 electrons (total 5 electrons in 2p orbitals)that will be filled according to Aufbau principle and Pauli exclusion principle in sequence of orbitals as in A.Thus there will be no electron in antibonding orbitals.

O2^+ will have total 15 electrons(total 7 electrons in 2p atomic orbitals).So, there will be 1 electron in antibonding 2p orbital.

C2^+2 have only 2 electrons in 2p atomic orbital.So, there will be no electron in antibonding orbitals.

Br2^+2 have total 8 electrons in 2p atomic orbitals.So, there will be 2 electrons in antibonding 2p molecular orbitals.
