br

The combination of /b/ and /r/ on 4chan, caused by the massing of /b/tards due to several of many reasons, ranging from /b/ closing down, a raid, or just the migrating of the 4chaners.

/b/ is dead? Go to /br/!

/r/ is infected by /b/. I declare this madness /br/.

Br Jude

Br Jude is the nicest teacher in LSC. Ever. According to Jasper, Br Jude doesn't speak in the lessons. Or more precisely, he talks in a way so advanced that we normal people can't understand. He found a way to solve this problem. In his lessons, he gives us videos to watch and tells us to self learn, when we can't understand the questions, he doesn't care. In the exams, we get low marks, he still doesn't care. We love this teacher so much!

(Br stands for Brother)

Br Jude lesson he gives out the test paper.

Br Jude: (calls our student numbers) Number thrie!

Number three goes out to get the test paper.

Br Jude: Number Dee!

All studnets: ???

CHX-Br

CHX-Br is short for cyclohexyl bromide (or CycloHeXyl Bromide). Cyclohexyl bromide can react with sodium ethoxide (NaOEt) and ethyl acetoacetate (EAA) to form Ethyl 2-cyclohexyl-3-oxobutanoate. Then react with hydrochloric acid to get 2-cyclohexyl-3-oxobutanoic acid. Heating it up will get you Cyclohexyl-2-Propanone (CHX2P, Cyclohyxylacetone) , a useful intermediate in the synthesis of Propylhexedrine, and carbon dioxide as a side product. Propylhexedrine is good orally in doses of 60mg to 180mg+ to decongest the nose, as a pre-workout, and to lose weight. Cyclohexyl bromide can also undergo other chemical reactions such as turning it into Cyclohexyl magnesium bromide and reacting it with Propyl chloride to get 1-cyclohexylpropane (unless there's rearrangement to 2-cyclohexylpropane).

Tony: I synthesized Cyclohexyl-2-Propanone (CHX2P) using CHX-Br and ethyl acetoacetate.
