Draw the curved arrow mechanims for the reactions of but-1-yne with catalytic trifilic acid in water to form butan-2-one, I just can't seem to figure out the last step! Thank you in advance! Draw the curved arrow mechanism for the reaction of but-1-yne with catalytic triflic acid in water to form butan-2-one. Follow the instructions under the boxes for each step. Draw all electrons and charges if necessary on all structures, do not show any inorganic side products Add any...
Three resonance structures of the following structure are possible. One resonance form is given below. Draw the remaining resonance structures, in any order, including nonbonding electrons. Omit curved arrows.
This structure could react with water to form a hydrate. Draw the mechanism of hydrate formation. Add the water molecule needed to the above reaction. Include curved arrows, intermediate structures, and the structure of the final product. When appropriate, use a water molecule or H3O+ to move a proton. н
a. Draw the structure of the tetrahedral intermediate INITIALLY FORMED in the reaction shown. • You do not have to consider stereochemistry. • Do not include counter-ions, e.g., Na", I', in your answer. • In cases where there is more than one answer, just draw one. ChemDoodle h. Draw the structures of the final acyl transfer products obtained. b. Draw the structures of the final acyl transfer products obtained. • You do not have to consider stereochemistry. • Draw organic...
7. One way for the triarylaminium cation radical mediated oxidation of Ar CH2OH to form ArCHO begins in Art Ar the manner shown here. (a) Draw a structure resulting from the curly arrow formalism. (b) Continue the sequence, the next two steps being loss of a proton and an electron. Draw the resulting structure. That structure when treated with a base (B: ) leads to the aldehyde and Ar3N: (the neutral form of the mediator). (c) Use the curly arrow...

(9 points) H H NH2 H OH HO F F OH O HS OH 13. Shown below is the formal structure of the amino acid methionine and its structure as it exists at physiological pH ( 7.3). In each case, the molecule itself is neutral; however at pH 7.3 there is an atom...
Multistep reaction mechanisms Group ActivityTreating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br-Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2ODraw a mechanism for each step. Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.
Two major resonance structures are possible for the following anion. One resonance form is given below, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Which structure contributes most to the hybrid? Both contribute equally. The structure with the negative charge on nitrogen. The structure with the negative charge on carbon.
Part 1 involved MeOH addition to form the key tetrahedral intermediate. Part 2 involves loss of H2O from the Map tetrahedral intermediate to form the ester. Part 2 of 2 Intermediate species (from Part 1); Add two curved arrows for the next step. Hö: CH3 er all remaining steps in the mechanism: 1) Draw each species (organic and inorganic) resulting from the previous step. Each step will include all of, and only, the atoms given in the first step i.e.,...
