module 6 (part 2) Flashcards
1
Q
what does no neighbouring protons suggest
A
no change in external magnetic field strength
therefore one peak will be present
2
Q
what are the -OH and -NH2 bonds in terms of chemical shift peak
A
labile
can be rapidly exchanged with neighbouring molecules
therefore their chemical shift is variable
3
Q
how do we remove the labile particles
A
add D2O
D2O is involved in proton exchange
4
Q
give the equation for the addition of D2O into a solution of ethanol
A
CH3CH2OH + D2O <=> CH3CH2OD + HOD
5
Q
A
