Answer:
D.
Explanation:
Hello,
In this case, the isomer of an organic compound is another organic compound having the same molecular formula but different structural formula, thus, the given compound's molecular formula is C₅H₈ since it is an alkyne due to the triple bond. Next, we analyze each option:
A. C₅H₁₂
B. C₅H₁₀
C. C₅H₁₀
D. C₅H₈
For that reason answer is D. based on the molecular formula as well as due to the presence of the triple bond unsaturation (alkyne as well).
Best regards.
An acid, acids have a pH less than 7
Answer : The equilibrium constant for this reaction is, ![K=\frac{(K_b)^2}{K_a}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%28K_b%29%5E2%7D%7BK_a%7D)
Explanation :
The given main chemical reaction is:
; ![K](https://tex.z-dn.net/?f=K)
The intermediate reactions are:
(1)
; ![K_a](https://tex.z-dn.net/?f=K_a)
(2)
; ![K_b](https://tex.z-dn.net/?f=K_b)
We are reversing reaction 1 and multiplying reaction 2 by 2 and then adding both reaction, we get:
(1)
; ![\frac{1}{K_a}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BK_a%7D)
(2)
; ![(K_b)^2](https://tex.z-dn.net/?f=%28K_b%29%5E2)
Thus, the equilibrium constant for this reaction will be:
![K=\frac{1}{K_a}\times (K_b)^2](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B1%7D%7BK_a%7D%5Ctimes%20%28K_b%29%5E2)
![K=\frac{(K_b)^2}{K_a}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%28K_b%29%5E2%7D%7BK_a%7D)
Thus, the equilibrium constant for this reaction is, ![K=\frac{(K_b)^2}{K_a}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%28K_b%29%5E2%7D%7BK_a%7D)
