The picture below is an example of how this assignment should be
done.
This experiment involves the synthesis of a target molecule using Grignard reagents. You must do the following: 1. Perform a retrosynthetic analysis on the target molecule. The organic starting material (what you have to work backwards toward) is provided. Draw a retrosythetic scheme; use the rightwards double arrow to show functional group transformations and disconnections. Provide synthons and synthetic equivalents for every disconnection made. 2. Propose the...

Predict which proton in ascorbic acid is the most acidic.
Identify the appropriate atom by selecting each atom and
assigning it a map number of 1 until all atoms are mapped. To do
this, right-click on an atom and choose Atom Properties. (Mac
users: Use an equivalent for right-clicking.) Then, clear the
check mark to enable the Map field before entering a value.
Draw the form of ascorbic acid that is present in the body
(aqueous solution, pH = 7.4)....
