4. (a) A WileyPlus problem from the (now defunct) Ch. 21 assignment I used to give asked about the product formed from the aromatic nitrile below upon reaction with amide. Their product was actually quite different than mine... That said, both have plausible mechanisms to support their formation. Propose two different mechanisms to explain the formation of the two different products (don't bother drawing the mechanism of the acidic workup that's Ch. 16). (9 points) WP answer 2 equiv KNH2...

Many times in Organic chemistry, two competing products are observed in a chemical reaction. The favored product is a result of the reaction being under Thermodynamic or under Kinetic control. Which of the following are characteristic properties of a reaction under Thermodynamic control? a. An endergonic reaction in which the products are less stable than the reactants. b. A reaction where the two products can be easily interconverted in a reversible process. c. A reaction where the product that is...

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...

Question The malonic ester synthesis has been used countless times to make bioactive molecules. One example is the synthesis of barbiturates. Your answer O a. = OEt Ob. Barbiturates are sedative-hypnotic drugs, which can have many effects ranging from sedation to anesthesia, and even death by acting as central nervous system depressants. Barbiturates are commonly prescribed medications, but are also for several non-therapeutic purposes (often illegally). = Et One particularly famous barbiturate is sodium thiopental, which has been used in...

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...

Synthesis of dimedone This lab exercise will give you practical experience with the generation of a malonic ester enolate and subsequent reaction with an a,p-unsaturated carbonyl compound. This sequence is known as the Michael reaction. In the presence of sodium methoxide, dimethyl propanedioate (malonic ester/dimethyl malonate) is converted to the corresponding enolate anion and reaction with 4-methylpent-3-en-2-one (mesityl oxide) affords the Michael adduct 1, as shown in the reaction sequence below. Under the basic reaction conditions, the Michael adduct 1...
