H Choose the best explanation for the proposed curved arrow mechanism for the second step of an electrophilic addition reaction of butadiene with aqueous acid. H H 0-H A) The cation is in equilibrium between two positions of the electrophile. The water atom attacks whichever position currently has the positive charge. B) The cation rapidly switches between two positions of the electrophile. The oxygen atom moves to whichever position currently has the positive charge. C) Attack of the water on the cation repels the positive charge, flipping it to the other end of the double bond. Attack at the other end flips the charge back again. D) The cation is found simultaneously in two positions of the electrophile. The electrons from the lone pair are attracted to either of these positively charged positions, forming an oxygen-carbon bond.

Choose the best explanation for the proposed curved arrow mechanism for the second step of an electrophilic addition reaction of butadiene with aqueous acid.

H Choose the best explanation for the proposed curved arrow mechanism for the second step of an electrophilic addition reaction of butadiene with aqueous acid. H H Ö-H A) The cation is in equilibrium between two positions of the electrophile. The water atom attacks whichever position currently has the positive charge. B) The cation rapidly switches between two positions of the electrophile. The oxygen atom moves to whichever position currently has the positive charge. C) Attack of the water on the cation repels the positive charge, flipping it to the other end of the double bond. Attack at the other end flips the charge back again. D) The cation is found simultaneously in two positions of the electrophile. The electrons from the lone pair are attracted to either of these positively charged positions, forming an oxygen-carbon bond.
