Hi sir, if in the exam they asked for the definition of a neutralisation reaction what would i say? A reaction where an acid and base react to form salt and water if what i would say but in the example at 5:06 no water is formed?
How come in the OCR textbook it says that amines can be formed from ethanolic ammonia and NaOH? First by an addition reaction to form a salt, then excess NaOH to form the amine - I don't think it's mentioned in the spec itself but it's on the textbook so should I stick to saying that excess ethanolic ammonia is enough to make amines?
So i assume it's like this or is there another reason? N is used when one of the H of the RNH2 group is substituted with an R' group N, N is used when both of the H of the RNH2 group are substituted with a R' groups
you're MY chem guy xx
second that
Love this.
Thank you so much.
I have an exam tomorrow.
This video will help me a lot.
Great channel my G best a level chem one i have found
Charles Butt Lovely stuff! Thanks 🙏🏻

This was tooo helpful 🙏🏼
why is is 6 moles of hydrogen for the aromatic amine?
Do you have to put the + charge on the nitrogen directly or at the end of the NH3 group? Thank you!!!
omg! im watching a foriegn channel!!.... but anyway good sir!!!...love from India..xox
For the reaction of haloalkanes with ammonia to produce primary amines, instead of the NH4+Cl- can we not just put HCl?
nadia You can but I wanted to get across excess NH3 idea. Both equations seen in text books
I see! Thank you :)

Gillian Ethanolic ammonia is fine. Are you on Twitter/Instagram? I’ll post the official OCR reaction pathways for you
MaChemGuy I have neither :( If you post it on twitter i think i can still see the post though
Gillian Just posted. Same name of course!
MaChemGuy Thank you so much! Appreciate all the effort :)

N, N is used when both of the H of the RNH2 group are substituted with a R' groups
Correct :)
Top man
For the naming exercise, would examiners allow N-butlydipropylamine as an answer?
No don't think so as the longest parent carbon chain is 4 carbons so it would have to butylamine instead of dipropylamine.
Legend
thank you!
Mairead Monaghan You’re welcome!
what does the N meant in front of the name?
N means the alkyl group is bonded to the nitrogen instead of being part of the carbon chain.
Hi sir, do we need to know about reaction of phenyl amine to diazonium ion? I saw it in a qs and was rlly confused.
Not on spec anymore
@@MaChemGuy oh great ty, can they not ask as application?
@@ammarafahad8094 Yes but all the information would be supplied in question
@@MaChemGuy ok tyy
Is this a year 2 topic?
For OCR yes. All organic Nitrogen compounds taught in second year
♥️♥️
Eman Raafat Glad you approve! 😊
is it something you just need to know?
I guess so (at this stage)
