N2+ Hybridization: An Explanation

[Rahat34]

N2+ is sp2 hybridiztion (it is scientifically correct)
Can anyone explain this ?

 

[AGNuke]

Write its electronic configuration, draw its box configuration and see if you can make a hybrid orbital by combining some valence orbitals.

 

[Rahat34]

i tried but the hybridization of atom N (with positive charge) comes out to be sp.

 

[DrDu]

Do you mean N_2^+ or N^{2+}, to begin with?

 

[Rahat34]

N₂⁺.nitrogen molecule with 1 electron removed.

The choice of the hybridization of an atom in a compound is a freedom you have and not something that is determined by some scientific law. Why do you want to use hybrids at all in the description of this molecule? s orbitals are full and don't contribute to bonding in a first approximation.
The two p_z orbitals along the molecule axis (z-axis) form a sigma bond and the rest of the electrons occupy the p_x and p_y orbitals forming a two and a one electron pi bond.
Maybe bond energy increases somehow if you allow for some hybridization between the s and the p_z orbitals. However without quantum chemical calculations, it is hard to say to what extent hybridization will increase bond energy.
