Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...

EXPERIMENT # 2: ORGANIC STRUCTURES AND MOLECULAR MODELS B. Bond Lengths and Resonance TeGaussian molecular modeling software utilizes the sophisticated Molecular Orbital Theory to predict the optimal geometry of molecules in the gas phase. Techniques used are theoretical predictions rather than experimental results. With the help of your instructor, use the Gaussian program to investigate the bond lengths of ethane (C,He), ethylene (CH), acetylene (C H2), and benzene (C&Ha). In each case build...
