想請問這題的醚和胺的沸點可以如何排序？ 因為我印象中氫鍵的影響比極性大，因此不了解為什麼胺的沸點比醚小 謝謝🙏

56. List the following compounds from highest boiling to lowest boiling: NH₂ 分子量 - * b₁p= HB dipole 為何 ↓ relatively weak HB OH ⑥ dipole-dipole interactions Q= LOH has two groups that hydrop bund ~HNY WH HB的影響力不是通常大於極性嗎? OH Obme electronegative thun N, OH Ingen bond are stomper than NH₂ primary amines form stronger hydrogen bond than seculary relatively weak no bydrogen had hydrogen bonds HB→分子量(分散戶 nly dipic dipole →接觸面積→極性 hah no hydrogen bon weaker dipole-dipole interactions tha oxygen-containing compounds because N is low electro negative than O

想請問這題是如何解出來的？ 手寫的圖是我嘗試解的過程，但沒有解出答案，麻煩大家了🫠

21. A metal ion in a weak-field octahedral complex has two more unpaired electrons than the same ion does in a strong-field octahedral complex. Which of the following could the metal ion be? (A) Cr³+ (B)Mn²+ (C)Co²+ (D)Ti²+ (E)Cu²+

想問這幾題 抱歉沒有解答 真的不太會連續迫近法 謝謝大家

B. [4 pts) Calculate the pH of a 0.02 M H₂A solution. If this H₂A with Kaf100 and Kaz= 4.0 x 10-² -5 C. (5 pts) Calculate the [H*] in 2.0 x 10¹5 M HA, if this HA with K₂ = 4 x 10-6. [Successive approximation should be needed). Q 3, B. [show calculation). Consider a weak acid HA with a Ką value of 4 x 10-6. Calculate the pH of a solution that contains 4.0 x 10-6 M HA and 4.0 x 10-6 M NaA. [Successive approximation should be needed). Show your Successive approximation

求詳解謝謝各位🙏

28. Which one of the following will have the greatest number of unpaired electrons ? A. B. C. [Mn(H2O).]2+ (weak field) [Fe(en)3]3+ (strong field) [Ru(NH3).]?* (strong field) (Cr(CI).]*- (weak field) [Fe(en)3]** (strong field) D. E.

微積分問題

13. Please find the limit (if it existes) of limx-o l! If it does not exist, explain why? 14. Please find limx-2([]x]] + [l-x[]). 15. Please find all asymptotes of f(x) = - 1 = x+2

想問問看大家這題普化😭

Crjticat Thinking ) The text states that “the pKa of 和e weak acid selected for the puffer shoujd be as close as pos- sible to the desired pH.”What 1 the pK, is not close to the desired PH? What is the problem with choosing such a weak acid used um 出e buffer?

普化問題 麻煩大家ㄌ🥺🥺
