Concept explainers
Interpretation:
Curved arrow notation and the products for all elimination steps are to be drawn, and the major product from all products is to be predicted.
Concept introduction:
In the nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This is the electron rich atom, and the less electronegative atom bonded to an electronegative atom is relatively electron poor. The curved arrow is drawn from the lone pair of electron rich atom points to the bonding region between the more electronegative atom and less electronegative atom representing the electron flow from electron rich site to electron poor site. The second curved arrow is drawn to represent the breaking of bond between the less electronegative atom and the leaving group to avoid exceeding an octet on the less electronegative atom.
If the leaving group is a stable ion species, the product is a major product.

Step 2: Draw the products of the acid-base reaction. Step 3: Draw the curved arrow mechanism of the acid-base reaction. Step 4: Determine the direction of equilibrium. Step 3: Draw the curved arrow mechanism of the acid-base reaction. So far, we have determined the products of the reaction. H H H-Br: A :Br: H-N-H H Next, lets approach drawing the curved arrow mechanism. A curved arrow mechanism represents electron movements and keeps track of bond forming and bond breaking reactions between compounds. Curved arrows must start from an electron source, either a non-bonding electron or bond and point towards an atom or bond. Where will the curved arrow in the mechanism start? the lone pair on bromine the H-Br bond the N-H bond the lone pair on the nitrogenarrow_forward
