Butanone - Wikipedia
Butanone Butanone, also known as methyl ethyl ketone ( MEK ), [a] is an organic compound with the formula CH 3 C (O)CH 2 CH 3. This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts. [7]

6.3 IR Spectrum and Characteristic Absorption Bands
-C-H (sp 3 C-H) bond of alkane gives absorption at about ~2900 cm -1 (see the example of the IR spectrum of 2-hexanone in Figure 6.3a; the C-H absorption band at about 2900 cm -1) A special note should be made for the C-H bond stretching of an aldehyde group that shows two absorption bands: one at ~2800 cm -1 and the other at ~ 2700 cm-1.

25/9/2022· Electronic Absorption Spectra. Aldehydes and ketones absorb ultraviolet light in the region 275-295 nm, and the result is excitation of an unshared electron on oxygen to a higher energy level. This is a n → pi∗ transition. A more intense pi → pi∗ transition occurs about 180 -190 nm. which corresponds to excitation of an electron from a
