(a.) For each of the following reactions, identify the nucleophile and electrophile and draw the electron motion arrows required to generate the product given. (b.) The spectrum above was measured on a sample with molecular formula C4H7ClO2. In the box in the middle of the spectrum, draw the structure of a conpound with this formula that is consistent with the spectrum above (there are wuite a few structures that woukd fit). Do not attempt to match the fingerprint region. (c.)...

9.1 Alcohols Worksheet Prior Knowledge: ✓ Acid/base definitions and pka values. ✓ Nucleophile/electrophile definitions and roles. ✓ Substitution and elimination reactions and mechanisms using curved arrows. Leaving group ability. Learning Objectives After completing this activity students should be able to: ✓ Predict the role of an alcohol in the Williamson Ether Synthesis and Fisher Esterification. Determine that protonation of an alcohol affords stronger electrophiles because of better, more stabilized, leaving groups. Conversion of Alcohols to Electrophiles Protonation RCH,OH + H...
Tulung ate n illud aludke place in a single step. In the Sn2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsey's rule whereby the more substituted alkene is generally formed. In E2 elimination,...
