My problem is I cannot see what is happening.

I believe it is a nucleophillic addition-elimination reaction/mechanism but I am unable to draw it out as I cannot see what to do.


[ATTACH=CONFIG]226192[/ATTACH]nnn

Here I want to know if it is ok to explain what is going on in words, if not I do not know the correct equation in stages to show how it progresses.


also how would you draw out these substances in display formula

(b)(i) Primary: CH3CH(NH2)CH3, Secondary: NH(CH3CH2)(CH3), Tertiary: N(CH3)3

aimed at question 1

aimed at question 2

this was to do with isomers

For question 2 you need to add an extra carbon and a nitrogen to
What nucleophile has these components?
What nitrogen nucleophiles do you know of?

For question 1 this is an acylation reaction, draw out the starting materials and have a go at drawing the product

I cannot see what you are trying to tell me

For question 1 this is an acylation reaction, draw out the starting materials and have a go at drawing the product

I know this from somehwere but I need some visual aid to trigger.

You need to add a carbon and a nitrogen to get your product.
This can be done by nucleophillic substitution of the bromine atom by a CN  nucleophile, do you know one?


Think about the structure of amides, can you draw one?

[Lego_12]

I honestly cannot do the first one could you help me by doing the 1st stage.

[discodermolide]

What you have drawn looks ok, but it is a bit upside-down!
The other one starts with the following reaction.
Now you figure out how to go from there to your product.

[Lego_12]

so are you sure I got the other one I just scanned up correct, can you check please?

[discodermolide]

The acetyl chloride acylated the amine to give the amide.

[Lego_12]

M-propylethanamide


Correct?

[discodermolide]

N-propylacetamide
Sorry I added an extra carbon which I will correct.

[Lego_12]

so it's N-propylacetamide

but my working out is good to support the fact that it was nucleophillic addition-elimination reaction

[discodermolide]

Yes, the mechanism you showed is fine.
