Indicate all products that are likely to form when tert-butyl bromide is heated in ethanol. Give the structure of any intermediate species

Imagine that phenol (“hydroxybenzene”) and nitrobenzene are reacted (in separate beakers) with a hot solution containing both concentrated sulfuric acid and concentrated nitric acid. A) Phenol reacts much more quickly than benzene, and benzene reacts much more quickly that nitrobenzene. Explain this observation, using at least one appropriate reaction coordinate diagram as part of your answer (be sure to label your reaction diagram with appropriate structures). You do not need to include any complete mechanisms, but you may wish to use portions of mechanisms as part of your discussion.

1-pentanol + HBr -> 1-bromopentane Is this substitution reaction reversible? In other words, would one expect to obtain an equilibrium mixture of the alcohol and bromoalkene at the end of the reaction of would one expect this reaction to go to completion? Justify your answer?

Provide the systematic name for each of the following isomeric esters with the chemical formula C-H1202. (Be sure to indicate double bond stereochemistry using (E)/(Z) notation. Indicate stereochemistry in rings with the terms cis or trans. It is not necessary to use italics in writing compound names.) ball & stick labels ball & stick labels ball & stick + labels

Ethylbutanoate undergoes hydrolysis with acid. What are two products? Ethanoic acid and butanol Ethanol and butnoate Ethane and butanoic acid Ethanol and butanoic acid None of these

Organic Chemistry Incorrect Separation Scheme Cannot be hand-drawn  *see attached for the incorrect separation scheme provided. The top of the separation scheme shows what other compound is mixed with your molecule (2,6-dimethyloct-2-ene). Assume for the purposes of this assignment that both compounds are solid at room temperature. Also assume that both compounds are soluble in ether, except ionic compounds.  The goal of the separation is the isolate each of the two compounds from the mixture. Below the incorrect separation scheme write a discussion of this incorrect scheme identifying all of the mistakes in the separation scheme. Keep in mind that there will be more than one mistake in the scheme. For each mistake, give a detailed, scientific explanation of why it is incorrect.

Industiral Chemistry Both Tetraethyl lead and methyl-t-butyl ether have been removed from or in the process of being removed from the gasoline additive industry. Explain why each of these compounds were used so highly, and why each is considered dangerous.

1. The acid-catalyzed elimination of an alcohol is an equilibrium reaction and requires special reac- tion conditions to favour the formation of the alkene product. What chemical principle controls the amount of alkene product that is produced? Provide two laboratory techniques that can be used to obtain good alkene yields in alcohol elimination reactions.

Provide a name for the molecule below and indicate whether it is the "diene" or "dienophile" Name: furan-2,5-dione It is a: dienophile

1) The carbon-oxygen double bond present in aldehydes and ketones is very polar. What does this mean and how does it arise? 2) The carbon-oxygen double bond is readily attacked by nucleophiles like cyanide ions or ammonia.           (i) What do you understand by the term nucleophile?           (ii) Which part of the carbon-oxygen double bond is attractive to nucleophiles? 3) Why is there a difference between aldehydes and ketones in their response to oxidizing agents such as potassium dichromate(VI) solution acidified with dilute sulfuric acid?
