All of the comments are so old damn, also thanks for the vid it was super helpful
Its hexan-1-ol in the first two exmaples, there are 6 carbon atoms in both examples
In Ind we Study know
Keep it up ❤
I got nothing to do in these holidays as I finished a levels , might as well watch these videos 😂
Hi, I still dont get why its a benzene ring attached to the CH2 for the shift at 2.9
No flames in organic chem laboratories. Most organic solvents are volatile and flammable. Yikes.
It’s a school
God bless , Thank you for these.
u are the best I got 122/140 on my y12 mocks because of u. And 17/20 on the MCQs as your videos have been so helpful.
@@evieiscool555 That’s awesome, well done you. Delighted I’ve been able to help 👍
Good Luck with yr2 (btw It's not as bad as people make it sound)
Hello James what’s up thanks for the video can’t wait to finish watching it
Cheers James
at 3:23 why do you not count the extra hydrogen on the carbon with the two methyls in the pink structure
Thank you so much, very helpful.
kelvin is 273 ryt ?? we learned as 273 when in absolute zero
Thank you James!! You have been the biggest help this year as a private candidate - all chem students should use your channel!
What a guy ❤🎉
Have you got any specific topics that usually come up on the depth AS paper rather than the breadth ?
You're the best chemistry help out there!!! Thank you have an amazing summer too 🧡💛🩵
It’s a pleasure James another year 🎉 and Tysm for all the support you have given this year your the best James and all the best Cheers
Thanks sir , enjoy your summer!
Thank you soo muchh 💓
We love you so much 😩
You helped so much haha I did some things in the morning of paper 3 from your channel which basically came up word for word, one question was literally identical 😂
😮
I begged my mom to watch this video
❤
Me
Youre the best A level chersmitry youtube channel in the world i mean it you are actually the reason i am going to pass my exams youre videos are the best they go into so much detail i swear they better than any ither yotuuber, honestly keep up the exellent work i hopee you know how much of a life saver you are youre genuinly the best person in the worlkd thank you so much youre stqarting to make me like chemsitry!
Thanks for that. Glad they are helpful. I’ll quote your comment next time I apply for a job 😊
Hey silent watcher here I but had to say thank you so much sir!!! Love the paper 3 synoptic playlist and your teaching videos massively helped me relearn everything this year. You’re so underrated for the work you do.
😂😂😂😂😂😂😂
Thank you so much sir , you have helped me so much in the last 2 years of chemistry thank you. Your playlist of all the questions walkthrough helped me so much thank you 🙏 ❤
Sir I just want to say a massive thank you for all the videos you've put out! They've helped me and I'm sure other people immensely! Keep going and thanks once again ❤
Did anyone else stuggle with the last question and the structures? I didnt even get time to finish it, i couldnt figure out some of the structures
I got all of them, but the cyclic one. I couldn’t figure that one out
@Khemani_RL that was the one i got stuck on. I was trying different things all the way until the end so ive definitely lost a mark there. Im sure its branched due to the way the question was worded but im not entirely sure
@@djdbakfneo2971 I experimented with so many different combinations of cyclic compounds based on the molecular formula and observations and I just couldn’t get it no matter how hard I tried 😢 Well at least I probably got 4-5 marks on that question
@@Khemani_RL same here, nothing seemed to work at all
I got cyclopentanol, 5C, each Carbon has 2 H’s except the one directly bonded to the OH group, it has 1. That makes 9H and then 1 O and 1 H from the OH group. I knew it had to be a primary alcohol but Cyclopentanol is secondary so its defo wrong, but its the only compound that fits the Mr that isnt branched and is alicyclic.
SPOT ON PREDICTIONS THANK YOUU SOM MUCH
I wouldn’t say spot on, but a large chunk of the list came up
@Khemani_RL Hmmm true... was on enough for me though 🙃
just finished paper 3 and wanted to say thank you so much for helping me this year!! you were honestly better than any tutor thank you so much for doing this for free
OCR really pulled an UNO reverse card with this one, I was expecting to breeze through it like Paper 1 and 2
Absolutely foul paper
@@ninaalmobaraki2005 nah fr, wtf was that entire phosphorous section
@soybouy_6668 tbh, it was pretty random. My other classmate really struggled with balancing the equations for that question
@@djdbakfneo2971 I did too, I eventually ran out of time before I could do it
@@soybouy_6668 exactly the same thing happened to my friend, that paper needed really to be 15 mins longer
Predictions were somewhat similar (i.e. chromatography, 6-marker on organic qualitative analysis and structures, chiral centre), but a lot of module 2 / 3 calculations and it felt thrown together in a weird way? But thank you so much for making all of this easier James!!
did you guys run oit of time
The amount of ads are ridiculous, this must be the best paid fucking chem teacher ever.
Let’s go chat
I'm gonna miss you mate really helped this year I believe I've got an A because of you but we'll see on the 15th August
1 hour until my 2024 chem paper 3 chat am i cooked
thanks so much! i'm about to head to school for paper 3 and i was panicking a bit about this LOL
