Answer:
true
Explanation:
Round characters tend not to show a lot of their emotions or feelings.
Answer:
CH₃CH₂CH₂COOH > CH₃CH₂COOH > ClCH₂CH₂COOH > ClCH₂COOH
Explanation:
Electron-withdrawing groups (EWGs) increase acidity by inductive removal of electrons from the carboxyl group.
Electron-donating groups (EDGs) decrease acidity by inductive donation of electrons to the carboxyl group.
- The closer the substituent is to the carboxyl group, the greater is its effect.
- The more substituents, the greater the effect.
- The effect tails off rapidly and is almost zero after about three C-C bonds.
CH₃CH₂-CH₂COOH — EDG — weakest — pKₐ = 4.82
CH₃-CH₂COOH — reference — pKₐ = 4.75
ClCH₂-CH₂COOH — EWG on β-carbon— stronger — pKₐ = 4.00
ClCH₂COOH — EWG on α-carbon — strongest — pKₐ = 2.87
Answer:
Shift it toward the products
Explanation:
Imagine this equilibrium:
2A + B ⇄ A₂B
Let's think the expression for Kc:
Kc = [A₂B] / [A]² . [B]
Now, we have this situation:
2A ↑ + B ⇄ A₂B
As we are not in equilibrium, we have to think that Kc would decrease.
↓Kc = [A₂B] / [A]² ↑ . [B]
so we have to use Qc (reaction quotient). For this case
Qc < Kc, so the reaction → Product side
We have to make more product to counteract the reagent increase and thus return the system to equilibriumr
