The addition of bromine and chlorine to a cycloalkane gives a trans-dihalocycloalkane. For example, the addition of bromine to cyclohexene gives trans-1,2-dibromocyclohexane; the cis isomer is not formed.

Addition of bromine to a cycloalkene is highly stereospecific; the halogen atoms always add trans to each other.

This week has been tough. I haven’t posted anything in a while because at the end of last week my school was hit with some really personal information and that last Thursday and Friday, everybody in school was emotionally exhausted, so it’s been tough. On Friday I did however leave school to attend the climate strike in my town and then I went to my boyfriend’s house because it was Valentines day. But to say I wasn’t hopeful at the start of this week to get loads of work done, would be a lie. I planned on doing a past paper for each of my subjects everyday - we were off for the week because it is mid-term - however, as per usual, I set up this workload thinking I’d actually be able to do it. I would love to say that I worked my ass off everyday this week, bu that would be the biggest load of bullshit ever; I didn’t properly start working till yesterday. I am proud of my chemistry notes I made yesterday, however, next week is our data tracking 3 (dt3) and on Monday I have biology...the one subject I’ve basically done nothing for. On Monday I have biology at 1:00, I have Tuesday off, Wednesday I have chemistry at 9:15, Thursday I have maths at 9:15 and finally on Friday I have physics at 9:15. I’m fucked. I don’t really know how to answer the questions from AS2 in biology and that whats most of the paper is going to be on. I also have physics homework but that won’t be due to till next week. On Wednesday afternoon my year has to go to this weird careers talk but I no longer have to go, but I already said I could, so next week is really not going to be a vibe. So I’m probably not going to post anything till next Saturday but I think that’s fair due to my exam timetable. Also not to flex but I’m proud of my chemistry mind-maps:

hey! I was just wondering if you have a master chart on all reactions covered in organic chemistry other then addition reactions, like ether synthesis? :O

My professor in first-semester organic chemistry was so helpful that he made “cheat sheets” for us. Bless his heart, I work with him now and he’s the best in the department here. So below I posted the four* roadmaps that relate to the first semester of organic chemistry.

Alcohol Synthesis Roadmap

Covers the different synthesis on alcohols and at the bottom right-hand corner introduces ether synthesis.

Alkyne Synthesis Roadmap

Alkene Synthesis Roadmap

Epoxide Synthesis Roadmap

[Look out for a complete master post on all synthesis covered in organic chemistry. Which will include the information above + carboxyl reactions, amine, reactions, and carboxylic derivative reactions!]
