Chemistry p41: How'd it go peeps?

i think you are right guys i misread the question i am so stupidd !!

This website calls them displacements, and they occur in order of reactivity. And F>Cl in terms of reactivity, right?

Don't worry, it was only 2 marks

 

[Autumngirl]

Sorry bromine went from -1 to 0 not +1. Displacement is definitely right.

 

[Abdel Moniem]

i wrote that equation based on electronegativity electrons are more held by the fluorine than to chlorine.

 

[randomcod]

I think the reaction was
KBr + FCl (it might have been KCl + FBr, but the product is the same) ->> KF + ClBr

But in displacements, it's reactivity what matters, I believe!

 

[Autumngirl]

Wait, what?! I got a different reaction. 2KBr + ClF=KCl + KF + Br2. Because both are more reactive than bromine.

Question 3 did you got the Ar as 24.33

Zayum
We certainly have variety here!
Whatever, it was only worth one mark!

Question 3 did you got the Ar as 24.33

Yep

 

[Abdel Moniem]

okay in question i dont remember what the questions were but i drew out a benzene ring with two alkyl groups and the reagent in the first steps was an acyl chloride

Yep

 

[Abdel Moniem]

what did you do in step 4 of that question?

 

[Autumngirl]

Wasn't step 1 when the alkyl groups turned to acid?

 

[randomcod]

what did you do in step 4 of that question?

Tin and conc HCl if that was what removed the Oxygen

 

[Autumngirl]

"Abdel Moniem, post: 919529, member: 41253"]what did you do in step 4 of that question?

I used LiAlH4. Amide to amine right?

 

[randomcod]

I honestly can't remember!

 

[randomcod]

I used LiAlH4. Amide to amine right?

Yep
LiAlH4 is a reducing agent too! I used Tin and Conc. HCl because it's the one in the textbook We're probably both right

 

[Autumngirl]

Haha ok. Let it go. Probably got it right. I don't remember getting confused there.
