. Alkanes, alkenes and alkynes all have C-C and C-H bonds which give IR peaks but do not have the same FTIR spectra. Explain how to tell the difference between alkane, alkene and alkyne FTIR spectra.
Homework Answers
Alkanes shows only one FTIR peak around 2900cm-1 that corresponds to C-H vibrations.
Alkenes have two FTIR peaks around 1600cm-1 and 3100cm-1 corresponding to C=C and =C-H vibrations.
Alkynes also have C Triple bond C stretching around 2100-2250cm-1 and triple bond C-H stretching vibrations around 3300cm-1.
Thus, by seeing the wavelengths of vibrations, you can differentiate between alkanes, alkenes and alkynes.
