Question
Nitrogen, N2, makes up about 80% of the earth’s atmosphere. Give the valence bond description of this molecule.
A) The nitrogen atoms are sp2 hybridized. A bond is formed by the overlap of an sp2 hybrid orbital from each N. The remaining sp2 hybrid orbitals contain lone pairs of electrons. The two unhybridized 2p orbitals on one N overlap with the parallel unhybridized 2p orbitals on the other N to form two bonds.
B) The nitrogen atoms are sp hybridized. A bond is formed by the overlap of an sp hybrid orbital from each N. The remaining sp hybrid orbitals contain lone pairs of electrons. The two unhybridized 2p orbitals on one N overlap with the parallel unhybridized 2p orbitals on the other N to form two bonds.
C) The nitrogen atoms are sp2 hybridized. Two bonds are formed by the overlap of two sp2 hybrid orbitals from each N. The remaining sp2hybrid orbitals contain lone pairs of electrons. The unhybridized 2p orbital on one N overlap with the parallel unhybridized 2p orbital on the other N to form the bond.
Explanation / Answer
The correct answer is option B)
B) The nitrogen atoms are sp hybridized. A bond is formed by the overlap of an sp hybrid orbital from each N. The remaining sp hybrid orbitals contain lone pairs of electrons. The two unhybridized 2p orbitals on one N overlap with the parallel unhybridized 2p orbitals on the other N to form two bonds.
