AQA A-Level Chemistry - Fractional Distillation and Cracking

[@i.buchanan]

"Right, so this video is going to cover organic chemistry" - I think that would be quite a feat for one video Mr. Rintoul ;) I don't usually comment but I just wanted to say how fantastic your videos are and how much they've helped me revise! I like my revision guide I've got, but I find it a lot easier to watch you go over topics than just reading them, and your explanations are always great and easy to understand :) I know you probably won't see this, but thanks for everything - you're a legend!

[@aaliyaha9171]

Seriously you have no idea how much these vidoes have helped me (i'm a auditory learner) i can't thank you enough but i've been recommending you to all my friends

Oh and the catalyst is a zeolite consisting of SiO2 and Aluminium Oxide (Dont know if it is AlO or AlO2) -You may be asked about their honeycomb structure which is just to increase surface area

[@MrERintoul]

You are absolutely correct - I was having a senior moment. The term aluminosilicate tends to be used to denote that the compound contains aluminium, silicon and oxygen. And you are also correct about the honeycomb structure! For me, I see that as more of an application question, but hopefully someone will read your comment and pick up an extra mark!

[@ibrahimshafi2064]

Don't know if you figured it out but aluminum oxide structural formula is Al2O3

I have my AS level exam tomorrow, and I had never understood this topic. I finally do understand, so thanks for the help!!

Thanks alot, was looking for aqa chemistry and found your videos to be very helpful !

This really helped for my exam for tmrrw really good explaining

[@ryanbower2005]

Love your videos man! Have to say though you got a bit vague at the end of this video, but thanks so much for doing what you do

[@MrERintoul]

Ryan Bower Thanks, Ryan! What got a bit vague...? Give me a shout and I'll try help if I can.

[@ryanbower2005]

just the bits about cracking with the zeolite catalyst and stuff

[@MrERintoul]

Ryan Bower Pretty sure that's all there on the video?

[@rgqwerty63]

thanks mate, just what I was looking for!

[@MrERintoul]

Not a problem.

[@mushroomsara304]

this video from 2014 helped me so much thank you my exam is next week >_

[@darkhacker8747]

How did it go? Anything you recommend to remember?

[@sophiakannathasan255]

is this video and your other videos applicable to the new a level chemistry syllabus?

[@skategirl555]

Super helpful, great explaining!

[@MrERintoul]

Mohammed Dakhl Allah It will be coming soon!

[@dakotafireshard7367]

in the text book it tells you each carbon chain and its uses? I've looked at the specification and it doesn't say if we need to learn their uses or not? do you happen to know? thanks very much for the videos

[@MrERintoul]

Dakota fireshard Hi, Dakota. I'm guessing that's not your actual name. But it's good. Dakota Snake-Eyes is pretty good too. But no, you don't need to know what the individual fractions are used for. Definitely not. Never.

[@IshtyaqKamal]

Just wanted to say you are correct polymerisation is in unit 2!

[@MrERintoul]

I always find it odd that at GCSE, cracking is followed by polymerisation, yet at AS, they are in separate papers!

[@IshtyaqKamal]

I think its because in AS cracking they don't really focus on the double bond so want you to learn more about it.

[@MrERintoul]

Syed Kamal True. But by bringing polymers and alkenes forward into CHEM 1, not only would you have all the basic hydrocarbons together, but you would also have all the isomerism together too!

[@AliHaider-us8fw]

Sir, it would be of great help if you could make a playlist for cie syllabus or give me method to do it myself.

[@tapi8091]

In the new spec we learn about addition polymerisation within this unit and l was wondering if you could do a video on it or explain it as l missed my lesson on it and l just don't get it.

[@MrERintoul]

+tapiwa kadzviti It's on the list to be done at some point!

[@The_Reductionist]

"In thermal cracking, high temperatures (typically in the range of 450°C to 750°C)" #chemguide will it matter whether we say 1000 degrees or 450-750, and if so which is more accurate?

[@MrERintoul]

Boby Gandhi I would stick with just saying high temperature!

[@The_Reductionist]

E Rintoul ok, thx again

[@dirtydiana9618]

Great video. Thank youuu again! :)

[@MrERintoul]

***** Not a problem, Diana!

[@francescamckendrick6917]

In my spec it says petroleum is a mixture of alkane hydrocarbons, I don't understand this as I thought petroleum was produced in the fractions and that the fractions didn't produce mixtures?

[@MrERintoul]

fcsc mck Strictly speaking, yeah, the fractions are mixtures. If you think about it, it kind of makes sense that way. Each level that is associated with a temperature will actually be a temperature range and so the resultant fraction will not be pure. However, for the sake of ease, it is often easier to think of a fraction consisting of a single length of hydrocarbon (although I can't imagine any question that would require differentiation between these 2 things). Has that helped at all?

[@francescamckendrick6917]

E Rintoul yes thank you that's helped a lot

[@George-rv2bs]

Really helped thanks.

[@alanabarlow6476]

Do you have a video on CFC's in the ozone layer please?

[@MrERintoul]

+Alana Barlow I think it's in this video: kzbin.info/www/bejne/hIm9YmBjns2WZ8U

[@GeeGeeGweppo]

Hey @ E Rintoul , as i was recapping this chem topic i came across you saying how haloalkanes have the same general formula + the halogen, so i was thinking with the example you gave , C = 1 therefore C1H4CL ? so that means the general formula doesn't work correct correct me if im wrong. Or does it work like if you have 1 Halogen you remove a H and so on. Cheers!

[@MrERintoul]

GeeGee Gweppo Hi! What I meant (I think...) is that they have the same general formula, but not that it is the same as for the alkanes! You're correct that you would need to remove a hydrogen and replace it with the halogen - and that only really works simply for the haloalkanes where there is just the one halogen bonded. That help?

[@GeeGeeGweppo]

I see thanks! i understand what you were trying to say now :) !
