Answer the following question given this paragraph: Valence bond theory describes the benzene molecule and other planar aromatic hydrocarbon molecules as hexagonal rings of sp2-hybridized carbon atoms with the unhybridized p orbital of each carbon atom perpendicular to the plane of the ring. Three valence electrons in the sp2 hybrid orbitals of each carbon atom and the valence electron of each hydrogen atom form the framework of bonds in the benzene molecule. The fourth valence electron of each carbon atom is shared with an adjacent carbon atom in their unhybridized p orbitals to yield the bonds. Benzene does not, however, exhibit the characteristics typical of an alkene. Each of the six bonds between its carbon atoms is equivalent and exhibits properties that are intermediate between those of a CC single bond and a C = C double bond. To represent this unique bonding, structural formulas for benzene and its derivatives are typically drawn with single bonds between the carbon atoms and a circle within the ring as shown in Figure 20.11. Q: Which theory describes the benzene molecule and other planar aromatic hydrocarbon molecules as hexagonal rings of sp2-hybridized carbon atoms with the unhybridized p orbital of each carbon atom perpendicular to the plane of the ring? A:
OPTIONS:
- hybrid orbital theory
- covalent bond theory
- molecular orbital theory
- valence bond theory
valence bond theory

Q: Answer the following question given this paragraph: Section Summary 1.1 Physics: An Introduction Science seeks to discover and describe the underlying order and simplicity in nature. Physics is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions. Scientific laws and theories express the general truths of nature and the body of knowledge they encompass. These laws of nature are rules that all natural processes appear to follow. Q: Is the most basic what is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions? A:
Answer:
