Organic

Question 1

TMS

Answer 1

Si(CH3)4 - 12 equivalent H’s in same chem environment
non-toxic and inert - wont react w/ sample + 1 signal
‘calibrates’

Question 2

n+1

Answer 2

no. neighbouring non eq H's + 1
= 1 singlet
= 2 doublet
= 3 triplet
= 4 quartet

Question 3

running a spectrum

Answer 3

dissolve solvent + put in tube

placed in a machine which uses radio waves in strong mag field

Question 4

chemical shift

Answer 4

field for tms - field measured / fieled for TMS X 10^6

high electronegativity = greater shift
