The peak around 3000-2750
is for the aldehydic C-H bond and and for the saturated C-H alkyl
carbons. But for the presence of aldehydic C-H there must be a
sharp peak of C=O around 1715 cm-1 but it is absent.
this clearly indicate that the peak present at near 3000 cm-1 is for saturated alkyl C-H bond.
The peaks in between 1500-1250 are for CH3 terminal groups.
This spectra is for some non-cyclic hydrocarbon without any functional group.

Please identify the main functional groups in the IR spectra of
two different molecules.
I can't figure out what the peaks in these IR signify. I don't
understand what the peak in the 3400 cm area of the second IR
is.
