Butanone - Wikipedia

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] It is partially soluble in water, and is commonly used

  13C NMR peak loion in butanone. The above is the correct X 13 X 2 2 13 C - N M R spectrum of butanone. In the X 13 X 2 2 13 C - N M R spectrum of butanone, I figure that the peak loions of the first ( 27.3 p p m) and third ( 35.2 p p m) carbons should be switched. Shouldn''t the third carbon be shifted upfield by the terminal methyl group
