Can you explain it? Provide examples with the various steps and explanations. How halogens affect the boiling/melting point? Does number of halogens affect it? For example, Ch3-Ch3 vs Ch3-Br vs Br-Ch3-Br

The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.

Alcohols are very useful organic compounds because there are many ways to synthesize larger and more complex molecules starting with simple alcohols. The reactions you will examine form a strong basis for synthetic tools that an organic chemist would use. You will be expected to predict the major products of reactions under the conditions given. The key to doing this is to look carefully at the conditions and remember how those conditions affect the products. It is a good idea to have an index card file of the reactions as you learn them. Dehydration (loss of water) - There are two forms of dehydration reactions with alcohols - ether formation and elimination (alkene formation). In both reactions you are looking for the components of water (OH and H) that will be removed in the reaction. Ether Formation - Two alcohols will form an ether link by loss of water forming an ether product with an acidic catalyst (typically H2SO4) at 140\deg C. One alcohol loses the hydroxyl group and one…

All electrophilic aromatic substitution reactions occur via a two-step mechanism: addition of the electrophile to form a resonance-stabilized carbocation, followed by deprotonation by a base. In the step shown below, loss of a proton to form the substitution product was drawn using the resonance structure with the + 1 formal charge at the ortho position to the carbon bonded to the electrophile. Redraw the step shown with the other two resonance structures and use curved arrows to show how these other two resonance structures can be converted to the substitution product by removal of a proton with the base shown. Part: 0/2 Part 1 of 2 H :CI-AICI, Draw the mechanism that generates the final substitution product with the +1 formal charge at the para position. Cl HC1 AICI3

4. A CHEM 245 student wants to synthesize some ethylene glycol to use as antifreeze in his radiator this winter. He proposes the following reaction to his instructor, who quickly explains that this reaction won't work as proposed due to the student's choice of reagent. 1) NaH 2) H20 OH Но a) Why can't sodium hydride (NaH) be used as the nucleophile in the reaction above? b) Propose an alternate reagent that COULD be used with the ethylene oxide to successfully give the desired ethylene glycol product.

methanol + CH3OH Suppose you were told that the above reaction was a substitution reaction but you were not told the mechanism. Evaluate the following categories to determine the reaction mechanism and then draw the structure of the major organic product. Type of alkyl halide: Type of nucleophile: Solvent: Is the product racemic?
