Question
The 4 ions A - D can be combined to make 2 ionic salts (2 ions per salt). One of the salts dissolves to become an acidic ion and a spectator ion (let's call this the acidic salt) while the other salt dissolves to become a basic ion and a spectator ion (let's call this the basic salt).
a) Select the 2 ions that form the acidic salt
A
B
C
D
b) Select all of the hydrocarbons (X-Z) that will react with the acidic salt extensively (in a one-to-one ratio.)
Remember: what the focus of this lecture is.
X
Y
Z
c) Select the species that is transferred to the acidic ion.
hydride ion
proton
d) In the JSME editor draw the resulting products by using the NEW tool. Draw your first product then click the NEW tool and lastly draw the other product (the order of input does not matter.) Do NOT include the spectator ion.
Input the SMILES string generated via the JSME editor. Remember that you should NOT use the X-window to add hydrogens - they are added automatically if needed.
e) Select all of the hydrocarbons (X-Z) that will react with the basic salt extensively (in a one-to-one ratio.)

f) Select the species that is transferred to the basic ion.
hydride ion
proton
g) In the JSME editor draw the resulting products from the transfer in f by using the NEW tool. Draw your first product then click the NEW tool and lastly draw the other product (the order of input does not matter.) Do NOT include the spectator ion.
Input the SMILES string generated via the JSME editor.Remember that you should NOT use the X-window to add hydrogens - they are added automatically if needed.
h) The hydrogens of the hydrocarbons X-Z are labelled a - g.
Select the most acidic proton

g
i) Rank protons b, d, f and g in decreasing acidity order (most acidic to least acidic.)
(most acidic) _ > _ > _ > _ (least acidic)
Explanation / Answer
The answer to part A is B and D. I promise--I'm working on this one too and I'm not getting the help I need in the forums. ;)
