Alkynes Contain a carbon-carbon triple bond, each sp hybridized and linear. … WebIR Spectroscopy Tutorial: Alkenes. Alkenes are compounds that have a carbon-carbon double bond, –C=C–. The stretching vibration of the C=C bond usually gives rise to a moderate band in the region 1680-1640 cm -1. Stretching vibrations of the –C= C–H bond are of higher frequency (higher wavenumber) than those of the –C– C–H bond in ... green pink yellow purple
