3. The nitrogen in ammonia has 5 valence electrons with a 2s2, 2p3 configuration. The 2s subshell contains a single pair of electrons and the 2p level is half full. These electrons undergo sp3 hybridization. The half-filled orbitals overlap with a hydrogen forming ammonia, creating the pyramidal structure associated with ammonia.
4. Each of the carbon atoms in ethyne only bonds with two other atoms. This means that when the carbon atoms hybridise their outer orbitals they only hybridise two of the orbitals. They use the single electron in the 2s orbital and only one of the 2p electrons leaving the other alone. The newly hybrid...
