- What reactions and reagents can be used to make phenol from benzene if electrophilic aromatic substitution reactions are excluded and benzene is the only source of carbon?Explain briefly the reactivity of aldehydes and ketones toward nucleophilic reagentsWhat explains why many aldehydes and ketones can undergo self- condensation reactions in basic conditions? The alpha carbon can lose a proton and act like a nucleophile and the carbonyl carbon a an electrophile O The alpha carbon can gain a proton and act like an electrophile and the carbonyl carbon is a nucleophile O The oxygen of the carbonyl group can attack the carbon of the carbonyl group Only esters can undergo self-condensation reactions
- Draw the structural formula of the enol formed in each alkyne hydration reaction; then draw the structural formula of the carbonyl compound with which each enol is in equilibriumWhy aldehydes and ketones do not undergo nucleophilic substitution reaction?Define the following terms Homolytic bond breakage: Nucleophile
- Rank the reactivity of the compounds below toward nucleophilic acyl substitution by writing the compounds' letters in the proper blanks in the box below. `NH CI Br CH3 CH3 A В C E rank compounds for acyl substitution reactivity most least reactive reactiveExplain the relevance pi* (antibonding) -molecular orbitals have in nucleophilic addition reactions of carbonyl containing compounds.describe how steric and electronic effects influence the postion of equilibrium when the electrophilic center of an aldehyde or ketone is under nucleophilic attack.
- What is the role of phosphoric acid in the synthesis of cyclohexene? it is an antioxidant that prevents free radical side reactions it is a safe, non-toxic solvent it lowers the boiling point of the reaction mixture (a colligative property of adding phosphoric acid to water) it protonates the hydroxyl of cyclohexanol to make it a better leaving group10. Why do aldehydes undergo nucleophilic addition reactions (rxns from Unit 10) while esters undergo nucleophilic acyl substitution (rxns from Unit 11) reactions? A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. B) Aldehydes are more sterically hindered than esters. C) Once the nucleophile adds to an aldehyde, the tetrahedral intermediate is too sterically hindered to eliminate one of the attached groups. D) The ester carbonyl carbon is sp3 hybridized while the aldehyde carbonyl carbon is sp2 hybridized. E) Once the nucleophile adds to an aldehyde, neither H- nor R- can be eliminated since they are strongly basic.Rank the following esters from most reactive to least reactive in the first slow step of a nucleophilic acyl substitution reaction (formation of the tetrahedral intermediate): Rank the same esters from most reactive to least reactive in the second slow step of a nucleophilic acyl substitution reaction (collapse of the tetrahedral intermediate).
