← ScienceWhich outcome occurs when molecular attractions dominate in chromatography?
A)Analyte retention time increases greatly✓
B)Eluent efficiency rises exponentially
C)Column stationary phase degrades rapidly
D)System pressure surges uncontrollably
💡 Explanation
Increased molecular attraction via **Van der Waals forces** causes analytes to bind more strongly within the stationary phase. Therefore, analyte retention time increases, rather than decreased elution efficiency, because attraction exceeds driving forces.
