Interpretation: The curved arrows are to be used to show the conversion of carbocation A to carbocation B. The new
Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the
Half headed arrows are used to show the flow of single electrons, while the full headed arrow shows the movement of electron pairs.
(b)
Interpretation: The product is to be drawn by using the curved arrows.
Concept introduction: Curved arrows aid in determining the movement and flow of electrons in the reaction. The electrons that take part in the chemical reactions are shown by the curved arrows. An electronegative element in the reaction attracts electron toward it.
Half headed arrows are used to show the flow of single electrons, while the full headed arrow shows the movement of electron pairs.

- Circle the correct bolded word. a. Hydrogenation of an alkyne with palladium on carbon can / cannot be controlled to give an alkene. b. When a reaction becomes more exothermic, the transition state looks more like the substrate / product. C. Addition of two equivalents of HBr to an alkyne results in a vicinal / geminal dibromide. d. An SN2 reaction involves the collision of two alkyl halides to form a new carbon-carbon bond. True / Falsearrow_forward4. Circle all TRUE statements, a. If the concentration of substrate is double the reaction rate will double in an SN2 reaction. b. A secondary alkyl halide is reacted with hydroxide, only substitution will occur. c. An "R" stereocenter is reacted with a nucleophile in an Sy2 reaction, the product has "S" stereochemistry. d. An SN2 reaction occurs faster at higher temperatures.arrow_forwardThe hydration reaction of 1-hexene includes the addition of water across the double bond, adding an alcohol group to the more substituted carbon. Sulfuric acid is used as the catalyst for the reaction, which donates a hydrogen. The resulting product is a racemic mixture of 2-hexanol. A. Draw the alkene hydration reaction and its product(s) using information given above. B. Please include reaction mechanism with arrows showing all steps resulting in product formation.arrow_forward
