Chloroalkane -----> alkanamine

[crayolé]

How does this reaction pathway work?
I always thought it was
C2H5Cl(g) + NH3(g) -----> C2H5NH2(g) + HCl(g)

but thats really wrong apparently :/ What are the catalysts/states and reactants?

[cindyy]

i thought that was right as well :S

[chansthename]

it is right

other info: alumina catalyst and 400 degrees are needed

[crayolé]

Thanks
Whats the chemical formula for alumina?

[cindyy]

Al2O3 i believe ...

[mankay]

Would we be required to know that catalyst is required?

[cindyy]

i would say so ... not 100% sure though

[chansthename]

it would be expected that for all reaction pathways you write the reactants, catalysts etc required as well as the states

[darkphoenix]

Nice i was just about to ask this question about what the catalyst would be. Thanks.

i don't think we need to know the catalysts/reaction conditions for this... it's not exactly spelled out for us so i assumed it wasn't even needed xD

[darkphoenix]

Hm doesn't hurt to know i guess?

It came up in a few prac exams i did, so im just gonna remember it in case.

yeah true. i didn't see anything in the tsfx nor my teachers notes about it though so i just assumed it wasn't needed, but maybe they will test us sneakily this year ~ who knows..

I thought that was for "Alkanol + NH3 --> H2O + Amine"

And that "Haloalkane + NH3 --> HX + Amine" needs no catalyst

[Greggler]

yeah i think the only reactions involving NH3/production of an amine dont even involve catalysts?

the only catalysts i have listed are
- sulfuric acid for esters
- permanganate/dichromate for carboxylic acid productino
- acidic enviroment for alkene + water = alkanol
- UV light for chlorination of an alkane
- 'catalyst' for cracking

please point out if ive missed any...

[stonecold]

thanks for reminding me to put acidified environment for water + alkene = alkanol

It applies for permanganate/dichromate as well.  you just need to write /H+
