Q

to predict the spectrum of an organic compound using the wavenumbers given to you, you have to

A
  • draw the compound you have to predict (what is it? eg aldehyde, alcohol…)
  • recognise the bonds present
  • use the table of wavenumbers given to identify the peaks which will be present in the graph

Q

to deduce the functional groups from a list of wavenumbers, you need to

A
  • find the range in which the values given fall

- match this value to the functional group in the data table

Q

you can deduce the structure of a compound using wavenumbers by

A
  • using the wavenumber values present to identify which functional groups are present
  • use the molecular formula given to draw the compound with the appropriate functional groups
