What hybrid orbitals are used by the N atoms in urea, H₂NCONH₂? A) sp B) sp² C) sp³ D) dsp³

Question

Quizplus · Accepted Answer

The central nitrogen atom in urea forms four sigma bonds with the surrounding atoms. In order to form these bonds, it hybridizes its three 2p orbitals and one 2s orbital. The resulting hybrid orbitals are three sp2 orbitals and one leftover unhybridized p orbital. Each of the two terminal nitrogen atoms forms two sigma bonds and has one lone pair of electrons. In order to accommodate these, each terminal nitrogen atom also hybridizes its three 2p orbitals and one 2s orbital, resulting in three sp2 orbitals and one leftover unhybridized p orbital. Therefore, the hybrid orbitals used by the N atoms in urea are sp³.
