âSorry for the paucity of posts over the past few days but I'm in a state of upheaval known as âjob changeâ.â âThere is no scheme in all these projects to solve the paucity of clean, safe drinking water.â âThe paucity of these qualities in the present Republic would stagger them.â
Benzene is the archetypical aromatic compound. It is planar, bond angles=120Âº, all carbon atoms in the ring are sp2 hybridized, and the pi-orbitals are occupied by 6 electrons. The aromatic heterocycle pyridine is similar to benzene, and is often used as a weak base for scavenging protons.
carbon sigma bond is formed from overlap of an sp3 hybrid orbital on each C atom. Ethanol, C2H6O has 2(4) + 6(1) + 6 = 20 e â The two C atoms and the O atom are sp3 hybridized. All bonds are formed from overlap with these sp3 hybrid orbitals. The CâH and OâH sigma bonds are formed from overlap of sp3 hy-brid orbitals with hydrogen 1s atomic orbitals. The CâC and CâO sigma bonds are formed from overlap of the sp3 hybrid orbitals on each atom. 16. HCN, 1 + 4 + 5 = 10 valence electrons Assuming N is hybridized, both C and N atoms are sp hybridized.
