Alcohols | A level Chemistry

[@HareshaGroves-tj4po]

Like I tried watching this video 5 times and I always fall asleep cause at some point I get confused but following in my textbook while watching kept me awake and now I have finally watched the entire video. The fact that I have actually done the experiments already brought back some prior knowledge that I couldn't explain, now everything makes sense. I still can't believe I went through and understand this in the space of 2hrs. Exams are like 3 weeks away and by this rate this channel will get me ready by then. Thank you.

[@chemistrytutor]

You're very welcome! Well done for working hard with it 👏

[@paulmorgan9753]

Great video. Covers everything a level chemistry students need to know about alcohols.

[@chemistrytutor]

Glad you think so! Thanks 😊

[@TheFrndly]

i never understood organic during my GCSES, however your playlist has finally allowed to me to understand it in a levels! thank you so much!

[@chemistrytutor]

That's lovely to know! I'm really pleased the videos are helping 😊

[@idontknowwhattonamethis75h82]

sir, this is the best video so far, and I will be watching pretty much all the a level vids from you first, thanks

[@chemistrytutor]

That's really lovely to know, thank you! Let me know if you can't find anything!

[@gracechen2412]

Sir, I can't thank you enough for your videos, you make sense what was impossible to understand! Do you think you can make explanation videos about carbonyl, carboxylic acid, esters, nitriles and some of other families in the organic chemistry?

[@chemistrytutor]

I'm really pleased the video is useful! Thank you for your feedback. I think I'll be prioritising exam question walkthrough videos for now. I'll try to do some for those topics!

[@kxkxsxi6305]

Love this video. Forever grateful for your videos ❤

[@alphacentral3509]

Dude Thanks A Lot, really appreciate the hard work you do to make these quality videos.

[@8StringsGuitar]

This was a great video, do you also have a video on esters and carboxylic acids as well?

[@chemistrytutor]

Thank you for the feedback! I dont have an Esters and acids explanation video yet. Its on my list though!

[@monishamohan1046]

Hi, thank you for making this really useful video! Please may you do the same for the Year 2 AQA A Level Chemistry syllabus (especially for organic)? 😊

[@chemistrytutor]

I'm working on that. Probably question walkthroughs for the near future

[@saahildarvesh1693]

Great vid… ❤ would you consider doing the same type videos for the caie syllabus instead? The code is 9701

[@chemistrytutor]

Thanks! I'll add that to my list. What I would say is that most of my content is transferable to all exam boards. I dont think there are huge variations

[@soyadrink9831]

Does the water have to be in gaseous state? Also, does the double bond from the alkene break by heterolytic fission? Thanks!

[@chemistrytutor]

For the hydration of alkenes? Yes water is a gas. And yes the pi bond of the double bond breaks and both electrons in the bond go to one carbon and it immediately uses them to bond to one of the H atoms in the phosphoric acid

[@makesan2827]

I think you forgot to cover the eliminations part of the video, may you please make a separate video on that please? 🙂

[@chemistrytutor]

Good spot. I'll add that to the list

[@devluharuwalla1943]

Love the video sir, can each oh group in an alcahol form one or two hydrogen bonds?

[@chemistrytutor]

In alcohols, the average hydrogen bonds per molecule is one. The limiting factor is the single delta + hydrogen

[@devluharuwalla1943]

Thank you so much sir. @@chemistrytutor

[@chemistrytutor]

@@devluharuwalla1943 😃 👍

[@soyadrink9831]

Sir, for the hydroxy example (5:57) would it be necessary to add the 2? since Aldehydes are always on position 1. Because I wrote: (2)-hydroxyethanal and then changed it to Hydroxyethanal because I believed it was unnecessary. Thanks!

[@chemistrytutor]

Yes indeed, you're correct. The 2 is not crucial for ethanal. That's why most mark schemes would show the (2-) in brackets as you've done in your comment. If it was essential, it would be 2-hydroxypropanal

[@natasha0074]

[@ahmediftikhar425]

I'm watching this preparing to give the 2024 May June 9701. Do you know if this still covers the entire syllabus? Or are some parts outdated?

[@chemistrytutor]

Hi. Is that CIE? I think you still need everything in this video. What I will say is that I structured this for the AQA course, so I think you have more of a Hydroxy topic which covers other things beyond this. So I think you need all of this... and more

[@ahmediftikhar425]

@@chemistrytutor Yes, the CIEs. Can you recommend where I should go to cover the rest? Mainly, I think I need to do Carboxylic acids, Esters, sp3 hybridisation.

[@chemistrytutor]

@@ahmediftikhar425 I'm not sure who is good for those I'm afraid. I'm sure you'll find some

Can you make vidio on aldehyde and ketones and all of there reaction

[@chemistrytutor]

I'd like to, but I'm not sure I'll have time before the exam, I'm afraid. I'll mostly be doing exam question based revision. I'll add an aldehyde and ketones question in for sure.

[@PatelHarnisha-g9j]

[@chemistrytutor]

@@PatelHarnisha-g9j that's lovely to know, thank you!

[@LBM24]

@5:41 hi why is it 2 hydroxy ethanal? i thought you always have to make it the smallest number possible?

[@chemistrytutor]

The aldehyde group gets position number 1. So the hydroxy has to be position number 2

[@billyb6]

Isn’t the combustion reaction C2H5OH + 302 -> 2CO2 + 3H2O So it’s not carbon neutral

[@chemistrytutor]

You can't determine carbon neutrality from one equation it's the balance of carbon into the plant, for instance, vs carbon out when you burn it. Photosynthesis, 6 CO2 in... 6CO2 + 6H2O --> C6H12O6 + 6O2 Fermentation, 2 CO2 out... C6H12O6 --> 2CO2 + 2C2H5OH Then combustion, 4 more CO2 out... 2 C2H5OH + 6O2 --> 4CO2 + 6H2O The 2nd and 3rd Equations add together and simplify to the precise opposite of the first

Thanks for the feedback. It's really lovely to hear that it's useful! I've mentioned carboxylic acids in the context of functional group Isomers, but I've not made a video about the whole topic yet. Its on my list!

[@makesan2827]

at 14:33 shouldnt C5H10 be pentene instead of pentane?

[@chemistrytutor]

Well done for spotting that inconsistency! In fact, the error lies with my hydrogens. I've written the Mr of pentane and hexane underneath the formula, but written the number of Hs as 10 each time!

[@sabriya1225]

thank you sm. Thats a good video, can you please also do a walkthrough of questions papers

Thank you! I've done quite a few walkthroughs, but not for whole papers. Here is a link to an overview document drive.google.com/file/d/1s3I5prjbJRR1U1lcKpXO9TQpQMaVoP66/view?usp=drivesdk
