Concentrated hydrochloric acid is not. What problem might occur if concentrated hydrochloric acid were substituted for phosphoric acid in the cyclohexene synthesis? allylic chlorination of the cyclohexene product may occur chlorocyclohexane may form as a byproduct the equilibrium will now favor formation of cyclohexanol by Le Chatelier's Principle hydrochloric acid is a weaker acid than phosphoric acid

(b) Draw the structural formula of the product formed by treating each Wittig reagent with cyclopentanone. Note that the functional group is an enol ether or, alternatively, a vinyl ether. (c) Draw the structural formula of the product formed on acid-catalyzed hydrolysis of each enol ether from part (b).Write a essay summarizing details and analysis of proofs for identification test for Qualitative Tests for carbonyls and Unknown carbonyl resulting in the final Unknown, which is benzaldehyde. Explain and describe in details all chemical test proof of benzaldehyde.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.

You do not need to include any complete mechanisms, but you may wish to use portions of mechanisms as part of your discussion.
- This question concerns adrenalin which is a hormone, a chemical messenger which stimulates the central nervous system. It's structure is shown below. It has a number of functional groups. What is a functional group? Identify and name the functional groups. Give the reagents and reaction conditions that establish the presence of any TWO of the functional groups present in adrenalinIn an experiment, triphenylmethanol is prepared using the Grignard reaction. The Grignard reaction involves preparation and reaction of a very nucleophilic organo-magnesium compound. The Grignard reagent is very reactive and is easily destroyed by reaction with atmospheric water, oxygen, or carbon dioxide. The Grignard reagent must be prepared under strict anhydrous conditions (dry glassware, dry solvent). The volative solvent, diethyl ether, helps to prevent oxygen or carbon dioxide from entering the reaction vessel. Reaction of bromobenzene with magnesium in ether produces phenylmagnesium bromide. This Grignard reagent then reacts with methyl benzoate to produce the corresponding alkoxide. Reaction of the alkoxide with aqueous acid then produces the alcohol. Why is it unwise to begin addition of the solution of carbonyl compound to the Grignard reagent before the latter has cooled to room temperature?In an experiment, triphenylmethanol is prepared using the Grignard reaction.
