(a)
Interpretation:
Missing curved arrows are to be supplied for the given proton transfer reaction. The relevant electrons are to be drawn if they are not shown.
Concept introduction:
In a proton transfer reaction, a proton is transferred from a Bronsted-Lowry acid to a Bronsted-Lowry base in a single elementary step in which one bond is broken and another is formed simultaneously. The curved arrow notation shows the movement of valence electrons, not atoms. The movement of two electrons is shown be using a double-barbed arrow. To represent bond breaking, the tail of the arrow originates from the center of a bond whereas to represent bond formation, the head of arrow points to an atom which forms the new bond, that is, σ bond or the region where the bond is formed if the new bond is a π bond.

IN Ill I -N S OMe D II H CO₂H 1/111 DuckDuckGarrow_forwardThese are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ?
