Look at the table in problem 20 – benzene (which only has London dispersion forces) has a higher boiling point than acetone (which has dipole-dipole and London dispersion forces). Therefore, the London

11: Free Radical Substitution and Addition Reactions
people.chem.ucsb.eduFree radical halogenation reactions of alkanes and cycloalkanes are substitution reactions in which a C-H is converted to a C-X. R3C-H + X2 → R3C-X + H-X While any of the molecular halogens F2, Cl2, Br2, and I2 will halogenate alkanes and cycloalkanes, Br2 or Cl2 are used most often. We will use bromination (X = Br) to illustrate alkane ...

people.chem.ucsb.edu7.1 Nucleophilic Substitution Reactions of Haloalkanes Nucleophilic substitution reactions are ionic reactions that break and make chemical bonds by transfers of pairs of electrons. We illustrate this using a general representation of a nucleophilic substitution reaction in which a halogen (X) is replaced by a new group (N).

In other words, an oxygen 2p orbital overlaps more effectively with the carbon 2p orbitals of the ring than an oxygen sp3 or- bital would.
