Look at the arrows below, and draw the intermediate that you get after pushing the arrows. After the two arrows are pushed, the negative charge of the intermediate is located on :
Options:
Answer:
C
Solution:
We need to interpret the arrows as a reaction pathway. The first arrow indicates that a lone pair from the HO- ion forms a new bond with the carbon atom of the C=O group. The second arrow shows the π electrons from the C=O bond moving onto the oxygen atom. The principle of charge conservation must be maintained: one negative charge enters the reaction, and one negative charge exits.
