Order the following stationary phaases by degree of polarity

Order the following stationary phaases by degree of polarity from low (#1 least polar) to high (#5 most polar):

a) 90% Bis-cyanopropyl 10% cyanopropyl phenyl polysiloxane

b) 5% Phenyl 95% dimethyl polysiloxane

c) Carbowax

d) 100% dimethyl polsiloxane

e) 14% cyanopropyl phenyl, 86% polysiloxane

a) 90% Bis-cyanopropyl 10% cyanopropyl phenyl polysiloxane ----- mid/high polarity

b) 5% Phenyl 95% dimethyl polysiloxane ---- non-polar

c) Carbowax - moderately polar

d) 100% dimethyl polsiloxane - non-polar

e) 14% cyanopropyl phenyl, 86% polysiloxane - low/mild polarity

So, the given stationary phases can be ordered by degree of polarity from low (#1 least polar) to high (#5 most polar) as :

#1 - d) 100% dimethyl polsiloxane

#2 - b) 5% Phenyl 95% dimethyl polysiloxane

#3 - e) 14% cyanopropyl phenyl, 86% polysiloxane

#4 - c) Carbowax

#5 - a) 90% Bis-cyanopropyl 10% cyanopropyl phenyl polysiloxane
