O₂N H KCN EtOH, H₂O O₂N OH NO₂) Which of the following compounds would have their equilibrium shifted to the greatest to the enol tautomer? d)Identify the electrophile and the nucleophile in each of the following reaction steps and then draw curved arrows to illustrate the bond-making and bondbreaking processes.
- Question: Draw the mechanism of the reaction you will complete in lab. Use the proper arrow drawingconvention to show all bond making and bond breaking steps in the reaction. Background info: A substitution reaction takes place when a nucleophile (Nu:) forms a bond with a carbonatom, displacing a leaving group (L).SN2 reactionLeaving groups are typically weak Bronsted bases that are stable as anions (often halide anions).The precise timing of when the leaving group leaves depends on the structure of the substrate –the molecule bearing the leaving group. Methyl and primary alkyl halides tend to undergo SN2type reactions. In this type of reaction, the nucleophile attacks the carbon from the side oppositethe leaving group and the nucleophile-carbon bond is made simultaneous with the carbon-leavinggroup bond breaking. SN2 reactions are one-step and there is an inversion of stereochemistry atthe carbon bonded to the nucleophile.SN1 reactionIf the carbon undergoing substitution is…Give the necessary reagents in the correct order, as a string of letters (Give cleat handwritten solution) Give missing reagent in the given reaction for all subparts!
