Question

Low solute retention in gas chromatography is loosely associated with:

A) low boiling points.

B) low vapor pressure.

C) high boiling points.

D) high molar mass.

E) high viscosity.

Answer 1

Option A

Ars option - A AL 1. Chromatography is the technique to separate mixture, or me Can say Isolate the pure compound. based on different types of chromatography technique 1. Cire there. 's Chromate geaply as used fer volatile compounds mainly.. The two phases are used mobile phase and Stationary phase. Mobile phase is gas here (innest like helium, Ne) solute means analyte here. ( injected in Vaporized) foom In ac separation is based on differences of boiling points À compound which boils at higher temperature than column temperature is going to spend neady all of its time condensed as a liquid so high boiling point means - High Retention time. . Low Retention time in Gc means low boiling point - Right ophien - A ® - This option is not right because low vapour pressure means high boiling point © -incorrect as above 0 - No relation to ac dependance - No relation to GC dependance

Answer 2

a is the correct anwer
