The following pre-lab tasks must be performed individually, typed and printed out and brought to the lab for the first experimental session. Do not use your lab notebooks for this purpose. 1. Using ChemDoodle software draw a reaction mechanism (appropriate arrows, transition states, lone pairs) of imine formation upon reaction of aniline with benzaldehyde. 2. Imines are important synthetic intermediates. Provide synthetic scheme -not mechanism (ChemDoodle drawn) showing synthetic transformation...

9 10-Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-II. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon...

CH 111 - Introduction to Inorganic and Organic Chemistry Lab 10 - Exp. 341 Synthesis of Strontium lodate In this lab, we will perform a synthesis reaction to generate a desired product. Synthesis reactions are performed in many different industries including fertilizers, plastics, pharmaceuticals and many others. The goal in a synthesis reaction is to generate and obtain as much of the desired product as possible. In this synthesis, the reaction between KIO, (potassium iodate) and Sr(NO3)2 (strontium nitrate) produces...
