Which of the two compounds has the higher Rf value?
Benzophenone has the higher Rf value Which of the two compounds is more polar?
Benzil is the more polar compound What are some of the possible explanations for the polarities of the two compounds?
Benzophenone is less polar because it has one carbon double bonded to oxygen that pull the
electrons in one direction however, the two benzene ring groups cause the overall compound to be
more non polar. On the other hand, benzil has two carbons that are each doubly bonded to oxygen
the oxygens pull the electrons away in different directions and this causes the compound to be more
polar. Though benzil also has two benzene groups, the oxygens pulling electrons cause it to be
overall more polar....
