Question 1

nmr define

Answer 1

relates to nuclear magnetic resonance, the spinning frequency of electrons and if its spin up or down

Question 2

IR define

Answer 2

Infared radiation causes vibrations in the bonds of molecules whihc creates movement. these movements are then associated with wave numbers which are based on length and bonds

Question 3

mass spec define

Answer 3

through mass spec, the molecule is fragmented into molecular ions which are charged. these fragments will go trhough a channel of magnetics and get bent and hit a detector. depending on the bend it will represent its mass to charge ratio and plot it on a graph

Question 4

what is conc.h2so4 do

Answer 4

it acts as a reactant/ source pf h+ ions

Question 5

IUPAC namign system

Answer 5

carboxylic acid
alcohol
amine
alkene,alykne,alkane
haloalkane

Question 6

HPCL

Answer 6

seperate components
qualitative analysis:
Determine the components in a mixture
Pure compound should be run through HPLC
Sample is run through HPLC under same conditions
If the two chromatograms have peak at same Retention time → likely compound is in the sample
quantitative analysis:
Run a set of standard solutions under the same conditions and use peak area to produce a calibration curve
Sample run through same HPLC
Compare the peak area to the calibration curve to determine concentration
