6.3 IR Spectrum and Characteristic Absorption Bands
WebExpert Answer The frequency of the C-H stretch is dependent on the hybridization of the carbon bonded to the hydrogen. The C-H stretch for sp2 hybridized carbon atoms … View the full answer Transcribed image text: 17. (4) The C(sp2)−HIR stretching absorption appears in the region 3000− 3100 cm−1. Webcausing IR absorption 3000-2800 (Note: The absorptions can be seen as several distinct peaks in this region.)

Lab Report 3 - Grade: A - Isoborneol Oxidation and Camphor
WebThe IR spectrum, shown in figure 3, shows a C-H sp 3 stretch at 3000-2800 cm-1 and a C=O stretch at ~1736 cm-1, which are both present in camphor. The IR spectrum also shows an impurity stretch at 3500-3300 cm-1. Because the stretch is similar to an O-H stretch, this impurity most likely came from water or ether still present in the final product. WebSep 24, 2015 · 4. "C-H" Stretching The aromatic "C-H" stretch is usually weak and occurs at "3100-3000 cm"^-1. The aliphatic "CH"_3 group shows stronger symmetric and antisymmetric stretches at "2960 cm"^(-1) and "2870 cm"^(-1). Here's the actual IR spectrum of methyl benzoate.
