Two compounds A and B from GC on two open tubular columns contains a XY-1 (100% methyl) and a XY-2 (50% methyl, 50% phenyl), with the same diameter, thickness and length under the same experimental conditions. The retention times and peak widths are show in the Table 1.Hint: phenyl groups interact more strongly with polar groups than methyl groups. Which compound is more polar? Explain your answer
