(a) Interpretation: The decreasing order of the acid strength should be determined. Concept introduction: The weak acid does not dissociate completely in a chemical reaction thus, the ionization equation is in equilibrium. For a general reaction of ionization of weak acid as follows: HA ⇌ H + + A − The expression for dissociation constant of the reaction is as follows: K a = [ H + ] [ A − ] [ HA ] The p K a of a weak acid is defined as negative log of K a or, p K = − log K a

Interpretation Introduction
(a)
Interpretation:
The decreasing order of the acid strength should be determined.
Concept introduction:
The weak acid does not dissociate completely in a chemical reaction thus, the ionization equation is in equilibrium.
For a general reaction of ionization of weak acid as follows:
HA⇌H++A−
The expression for dissociation constant of the reaction is as follows:
Ka=[H+][A−][HA]
The pKa of a weak acid is defined as negative log of Ka or,
pK=−logKa
Interpretation Introduction
(b)
Interpretation:
The acid with the largest Ka value should be determined.
Concept introduction:
The weak acid does not dissociate completely in a chemical reaction thus, the ionization equation is in equilibrium.
For a general reaction of ionization of weak acid as follows:

The expression for dissociation constant of the reaction is as follows:
Ka=[H+][A−][HA]
The pKa of a weak acid is defined as negative log of Ka or,
(EXM 2, PRBLM 3) Here is this problem, can you explain it to me and show how its done. Thank you I need to see the work for like prbl solving.
can someone draw out the reaction mechanism for this reaction showing all bonds, intermediates and side products
Comment on the general features of the 1H-NMR spectrum of isoamyl ester provided below
What would be the best choices for the missing reagents 1 and 3 in this synthesis?
1. PPh3
3
2. n-BuLi
• Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like.
• Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is.
• Note: if one of your reagents needs to contain a halogen, use bromine.
