Of the following, only _____ has unpaired electrons. The sp-hybridized O and N atoms form the weakest triel The sigma bond is formed from head-to-head A good general rule is that being less than about 12 eV apart in energy is required for orbitals to be close enough in energy. HCN. So for N2, each N has one lone pair and one triple bond with the other nitrogen atom, which means it … As both Hydrogen and Nitrogen are placed far from each other at bond angles of 180 degrees, it forms a linear shape.
