MCAT AAMC
When looking at paper chromatography correct answersfocus on the
stationary
if solute is phase-
same as stationary it will stop here, if opposite of stationary it will
elute (polar
vs
nonpolar)
Rf in paper chromatography correct answersratio of the distance traveled by
the analyte
relative to the solvent front during chromatographic
separation
If both cis and trans forms are produced then correct answersthe
reaction is not
stereospeci
fic
What functional group forms during peptide bond formation between
amino acids
correct answersan amide
group
The first peak in a gas chromatograph (gc trace) would be correct
answersthe
the one with weight or weakest intermolecular forces of
lowest molecular
attraction
-it would migrate the fastest making the
first peak
Thin lens formula correct answersS=
1/o
S is + 1/istrength of the persons
the
eye lens
Adding strong acid to weak acid will correct answersdecrease the amount
of ionization
the weak
acid
-eg adding HCl to CH3CO2H will decrease the percent ionization of
acetic acid
The index of refraction of a medium correct answersequals the ratio of the
speed
in of light
vacuum to the speed of light in the
n=
medium
c/v
Intensity correct answersis directly proportional to the number of
photons emitted
Energy of photon emitted correct
answersE=
h is 6.6x10^-34hf
f is frequency of
Js
radiation
E is energy of
photon
-THz is 10^12
Hz
Standard atmospheric pressure correct answers760
mm Hg
Acidic Side chains correct answers-are negatively charged at
high neutral
-are pH at low
pH
