Draw curved arrows to show the movement of the electrons in the following reaction steps.

Short Answer

Expert verified

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.

Step by step solution

01

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.
