A student attempting to sulfonate styrene (vinyl benzene) obtains a by product that contains neither sulfur nor oxygen atoms. Efforts to nitrate styrene yield identical results. Of the 2 diastereomers of this product identified by GC, one is crystallized and characterized. Its IR spectrum features prominent bands at 3050, 2950, 1615, and 1500 cm-1, and its 1H and 13C NMR spectra are summarized below. Identify the product, assign its NMR and IR signals to the corresponding protons and bonds, and propose a mechanism for its formation. (You do not need to determine or explain the stereo chemical configuration.)
Write conditions and reactions for the following conversions: (i) Chloroform into diethylcarbonate (ii) Phenol into salicylic acid (iii) 2-propanone into 2-inethyl-2-prop
Mesomeric forms are the possible locations of electrons at a single instant, if you get what I mean. Like, an adjacent double and single bond in a molecule. The resonance form, how
