1. a. Why would a column be ineffective if you chose an eluting solvent that was too polar? b. Why would a column be ineffective if you chose an eluting solvent that was not polar enough?

When a pure sample of tert-butyl bromide is analyzed by gas chromatography, two components are usually observed. One of them is tert-butyl bromide and the other one is a decomposition product. As the temperature of the injector is increased, the amount of the decomposition product increases and the amount of tert-butyl bromide decreases.a. What is the structure of the decomposition product?b. Why does the amount of decomposition increase with increasing temperature?c. Why does tert-butyl bromide decompose much more easily than tert-butyl chloride?

Which statement is true? Statement 1: In chromatography, the compound mixture moves along with the mobile phase through the stationary phase and the components get separated depending on the degree of interaction and adhesion Statement 2: Compound A is more soluble in the mobile phase compared to compound B. Thus, compound A would most probably have a higher Rf value.
