1. Define the term "Nucleophile" and explain how a Grignard reagent acts as a nucleophile. Briefly explain using a chemical equation, why it is necessary to use dry apparatus and reagents during the synthesis of C6H5MgBr. phenylmagnesium bromide. 3. By referring to a textbook, write a mechanism for the reaction between phenylmagnesium bromide and the ketone butanone. In a reaction of phenylmagnesium bromide with butanone the Grignard reagent was prepared from 25 g of...

Preparation of Triphenylmethanol Using the Grignard Reaction.
RH ROOH CO TO R-R MgBr 1.ether 2.11-SO/10 Icther Grignard reagents are highly reactive and can undergo undesirable RCOH TH₂O side reactions if impurities such as water, carbon dioxide, or oxygen are present. If the organohalogen is added to the R-Mg-X magnesium too quickly, undesired coupling reactions can also occur. In this experiment, you will use 0.015 moles of either benzophenone or ethyl benzoate as the recipient of the phenylmagnesium bromide and this...

1. Write the mechanism for the synthesis reaction for Nitration of Methyl Benzoate C₆H₅CO₂CH₃ + HONO₂ --------> C8H7NO4 H₂ O Methylbenzoate + Nitric Acid (H₂ SO4 ) Methyl m-nitrobenzoate water Write the complete mechanism for the reaction. Be sure to use expanded structural formulas for all chemical species. Include all bonds, non-bonding electrons, formal charges, and electron-flow arrows. DO NOT use bond-line formulas, but rather explicitly show atomic symbols. For this mechanism, show the individual resonance contributors for the arenium...
