Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

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...
