- Give reaction mechanism in clear handwritten on paper!arrow_forwardWhat happens when benzene and anisole react with sodium metal in the presence of ethanolic solution of ammonia. Also give mechanism for the reaction of benzene.arrow_forwardSuppose that the hydride ion transfer shown in the reaction is the rate-determining step. What would be the effect if the reaction is done on very basic conditions?arrow_forward
- Give the mechanism and productarrow_forwardOutline a synthesis of each of the following compounds from isopropyl alcohol. A compound prepared in one part can be used as a reactant in another. (Hint: which of the compounds shown can serve as a starting material to all others?)arrow_forwardIdentify the pericyclic reactions in the followingreaction schemes. Give the complete reaction name and indicate the course of the reaction with the aid of the arrow notation.arrow_forward
- 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) When chlorobenzene reacts with a hot solution of sulfuric and nitric acids, an interesting result occurs: the reaction is slower than the reaction of the solution with benzene – which is similar to the result of the reaction of the solution with nitrobenzene – but it generates products with the same substitution pattern seen in the reaction of the solution with phenol. Explain why chlorobenzene has this curious reactivity.arrow_forwardAlthough chlorine is an electron withdrawing group, yet it is ortho-, para¬directing in electrophilic aromatic substitution reactions. Explain why it is SO?arrow_forwardSuggest reasonable mechanisms for each of the following reaction.arrow_forward
- Observe and identify what's the general reaction scheme and explain it.arrow_forwardWhat is the product formes on the nitration of benzene, toluene, chlorobenzene and benzoic acid and give condition for eacharrow_forwardThe reaction is a nucleophilic substitution, A is OH- and B is an alkyl bromide. Give the reaction mechanism and explain your reasoning.arrow_forward
