獻給在感情中懷疑自我的人：你沒有錯，你只是成了他無法消化的好（You Were Let Go Because You Were Too Good）
- This doesn't have to be a sob or a denial or a bromide.
這不必是哭訴、否認或陳腔濫調。
日系偶像的日常是怎樣的？吉永愛莉的一天！ (A Day and Life of a Japanese Idol / Airi Yumesaki)
- I also choose a theme for the bromide every month, and decide where to shoot it.
我還會每月為溴化物選擇一個主題，並決定在哪裡拍攝。
10 大超危險時尚潮流！ (10 Dangerous Fashion Trends)
- In the 1930s, ladies in Paris could wear Thradia brand cosmetics, made from both thorium chloride and radium bromide.
在 1930 年代，巴黎的女士們可以購買 Thradia 品牌的化妝品，這些化妝品由氯化釷和溴化鐳製成。
- and radium bromide -- apparently, the more radioactive elements, the better.
SN1/SN2/E1/E2 機制怎麼選？讓你一看就懂！ (Choosing Between SN1/SN2/E1/E2 Mechanisms)
- So that's why the halides as well are very good, uh, leaving groups because, uh, bromide is perfectly happy on its own.
這也是為什麼鹵化物也是非常好的離去基團，因為溴離子單獨存在時非常穩定。
- We have the product, we have a water molecule, and a bromide.
我們有產物、一個水分子，還有一個溴離子。
E2 反應！ (E2 Reaction)
- So this is what's left: propene, and then we have water and the bromide ion.
所以最後剩下的產物是：丙烯、水以及溴離子。
鹵代醇的形成！ (Halohydrin Formation)
- So we know that when we do dihalogenation, what was going to happen next is that the bromide ion that we generated right here was going to go ahead and do SN2, pop open the bromonium ion,
所以我們知道在進行二鹵化反應時，接下來會發生的事，就是我們剛才產生的溴離子會去進行 SN2 反應，把溴鎓離子打開。
- Water is going to do SN2 just the way the bromide ion would have if we were in inert solvent.
水會像我們在惰性溶劑中時，溴離子會做的那樣進行 SN2 反應。
親電性加成反應：氫鹵化、水合、二鹵化！ (Hydrohalogenation, Hydration, Dihalogenation)
- And then the bromide from before, very easy, negative charge is attracted to a positive charge,
接著是之前的溴離子，這很簡單，負電荷會被正電荷吸引，
- and we're going to get our alkyl bromide.
然後我們就會得到烷基溴。
共軛多烯系統的加成反應！ (Addition on Conjugated Polyunsaturated Systems)
- So as a bromide approaches this system, it is not necessarily going to have a specific preference for this carbon over this carbon.
所以當溴離子靠近這個系統時，它不一定會對這個碳或那個碳有特定的偏好。
- So let's say that the bromide attacks this resonance structure and the bromide goes there.
假設溴離子攻擊這個共振結構，溴就會接到那個位置。
