IR6. Carbon Oxygen Double Bonds - Chemistry LibreTexts

WebJan 30, 2024 · The largest class of oxygen-containing molecules is carbonyl compounds, which contain C=O bonds. A C=O stretch is normally easy to find in an IR spectrum, … WebC–C stretch (in-ring) from 1500-1400 cm -1 C–H "oop" from 900-675 cm -1 Note that this is at slightly higher frequency than is the –C–H stretch in alkanes. This is a very useful tool for interpreting IR spectra. Only alkenes and aromatics show a C–H stretch slightly higher than 3000 cm -1. Figure 6. shows the spectrum of toluene. Figure 6. WebThe IR bands simply indicate the type of bond. The O-H indicates an alcohol, and the C=O indicates a ketone. Combined in one spectra they may indicate an organic acid or … fnaf 5 wallpaper
