Chapter 5: Q9TP (page 230)

Draw curved arrows to show the movement of the electrons in each step of the following reaction sequences.

Short Answer

Expert verified

The first step is to use a curved arrow.

鈥� As new covalent bonds are formed and existing covalent bonds are destroyed, electrons move in curved arrows.

鈥� Each arrow represents the movement of two electrons (an electron pair) from a single atom to an electrophile (nucleophile) at the end of the arrow (at the point of the arrow).

鈥� The arrow's tail denotes the location of the reactant's electrons; the tail always starts at a lone pair or a bond.

鈥� The arrow's head always points to an atom or a bond, indicating where these same electrons end up in the result.
