Question

Question: Draw the products that would be obtained by following the incorrect arrows in the box entitled “A Few Words about Curved Arrows” and explain what is wrong with the structures you obtain

Short answer

When arrows are drawn incorrectly, they result in a bromine with an incomplete octet and a positive charge, as well as an oxygen with 10 valence electrons and a 2-negative charge.

When the arrow is drawn improperly, oxygen with an incomplete octet and a 2+ charge results.

Step-by-step solution

 Drawing the arrow incorrectly for question a) -  

When arrows are drawn incorrectly, they result in a bromine with an incomplete octet and a positive charge, as well as an oxygen with 10 valence electrons and a 2-negative charge.

When the arrow is drawn improperly, oxygen with an incomplete octet and a 2+ charge results.

  Drawing the arrow incorrectly for question b) -      

The arrow is intended to illustrate where the electron moves to, yet there are no electrons on the H to go anywhere.

Drawing the arrow incorrectly for question c) –

Because the destination of electrons in the breaking pi-bond is unknown, the product cannot be drawn.

Drawing the arrow incorrectly for question d) –

The arrow is supposed to illustrate where the electrons flow to, but there are no electrons on the carbon to go anywhere, therefore it can't be drawn.
