A Level Chemistry Revision (Year 13) "Directing Groups in the Reactions of Benzene" (OCR)

You can find all my A Level Chemistry videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at directing groups in the reactions of benzene compounds. First we explore how the hydroxyl and amine groups can activate the benzene ring. We then look at how these groups direct substitution to carbons 2 and 4. Next, we look at how the nitro group reduces the reactivity of the benzene ring and how this directs substitution to carbon 3.

Always a great help, thank you

Great video

[@AndyPeterBird]

Amazing, this will be useful for revision!

[@Freesciencelessons]

Thank you. Many students find this a hard topic. I'm happy to be able to help them.

@@Freesciencelessons I have to agree

saved me in gcse's and doing it again 🙏

[@HineseStateTelevision]

Wow thank you so much

[@Freesciencelessons]

Thanks. I hope you found it useful.

Hi sir, was just wondering when you’d finish all Biology+Chemistry contents for OCR yr12&13???Thanks a lot.Since I’m in yr 12 right now.

[@Freesciencelessons]

I'm now into the Year 13 work so I think I should be completely done near the end of 2024/early 2025.

Do Relative abundance please 🙏

[@fatima.s4382]

Are electron withdrawing groups less reactive than benzene but electron donating ones more reactive?

[@Freesciencelessons]

Electron withdrawing groups are not more or less reactive than benzene. They make the benzene ring less reactive. Electron donating groups make the benzene ring more reactive.

hi sir, will you ever go through a level physics? many thanks

[@Freesciencelessons]

Hi. I'm afraid that I've never taught A level Physics so I have no plans to make videos for that.

[@claudioaguilar5135]

real shame, thanks anyway !@@Freesciencelessons
