A proton transfer reaction can involve a substance without non-bonding electron pairs as the electron-rich reactant. a. This is 2,3-dimethyl-2-butene. Draw a very minor resonance contributor that involves charge separation. Make sure you show all formal charges and non-bonding electron pairs. Show any curved arrow(s) involved to reach your resonance contributor. b. A proton transfer reaction can occur from hydrochloric acid to 2,3-dimethyl-2-butene. In the box below, put the structure of your answer from (a) next to
HCl
. Use curved arrows to show the mechanism of the proton transfer reaction based on the sample proton transfer reaction shown in the textbook. Then, draw the products of the reaction (Lewis structures or line structures accepted). Do not draw the transition state.
