am talking about this one on the ir spectroscopy we have carbon carbon double bond on benzen the three double bond so if we have that cant we say we have to csp2-H on the graph around 3100cm-1 thank u

For ethyl vanillin there will be FCC-C) = 1200 cm ²1
But overall IR spectra for both would remain
some what exy same.

Now as IR of both vanillin and ethyl vanillin are similar, NMR is
a better technique to distinguish between the two as NMR would
show different splitting patterns for ethyl, methyl substitution.
