When the Lewis structure of an ion is written, the entire structure is placed in brackets, and the charge is written as a superscript on the upper right, outside of the brackets. Acrolein test is a test for the presence of glycerin or fats. In acrolein, the inductive effect of the vinyl group isn't too big, plus there is an electron donating effect through resonance, so I'd expect it to be reactive to Fehling's reagent ... How to interpret spectroscopic data to obtain the structural formula? - 2C5NRH1 from Alamy's library of millions of high resolution stock photos, illustrations and vectors. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein.
