Concept explainers
(a)
Interpretation:
Movement of electrons should be indicated using curved arrows for the given reaction.
Concept introduction:
Mechanism of the reaction is the step-by-step description of the process by which reactants are changed into products.
Curved arrows show the bonds that are formed and the bonds that are broken in a reaction.
Curved arrows used to understand a reaction mechanism.
Curved arrows are drawn to show how the electrons move as new covalent bonds are formed existing covalent bonds are broken.
Each arrow represents the simultaneous movement of two electrons from a nucleophile towards an electrophile.
The tail of the arrow is positioned where the electrons are in the reactant; the tail always starts at a lone pair of electron or at a bond.
The head of the arrow points to where these same electrons end up in the product; the arrow always points at an atom or a bond.

Does it break at the same time that the new bond between the nucleophile and C forms? Or Does the bond to the leaving group break first.arrow_forward

Student A uses an aldehyde and a Lewis-acid catalyst. Students B and C use the same conditions, but without a catalyst. Student B also swaps the aldehyde for a ketone. Student A's reaction is the fastest, and Student B's reaction is the slowest. Based on these results, which factor(s) is/are affecting the rate of the reactions? Select all that apply.
