It was sn1 I can't remember where the carbocation was
why sn1?

Chemistry unit 2 6CH02 exam.How was it?

why sn1?
Because it was a tertiary halogenoalkane, so the surrounding methyl groups stabilise it

so will i get a mark ? as final product is same i guess
The question was out of 2 marks right? The marks tend to be for the curly arrows, but I guess you'll lose one for using the SN2 mechanism though
How was the rest of it?

if it doesnt show, they are gonna ask for the actual paper
I made sure that it is clear and dark so hope its ok

guys, it was definitely a secondary halogenoalkane for the mechanism.......

so it can be sn1 or sn2

sn2 is for 1 degree haloalkane and sn1 is for 3 degree haloalkane,,,but the question was 2-chlorobutane so CH3CHClCH2CH3 so 2 degree ,,,,now for 2 degree if it is c-cl bond then sn2 if c-i c-br then sn1 so chill out guys its sn2
haha, no.
for secondary halogenoalkanes, they will react by sn1 AND sn2. Although, sn1 is the dominant mechanism.
I think they should accept both

guys it said suggest the mechanism, calm down!haha, no.

and i put for the sodium chloride one thaty hexane cant get between the ions. then
for the HCL one, HCL disscoiates in H+ and cl- in solution, clocking the correct attracted cathode/anode if you get me..
the colour change was orange to colourless as you were going from bromine water to chlorine water

what did u guys put for the MCQ that was like why is sodium chloride more soluble in water than hexane?
also..
why do you acidify to prevent hydrolysis?
and on that question what was the colour change?
thanks
the energy released during hydration is greater than the lattice enthalpy
I checked the equation and it was like
Br2 + H2O <==> 2H^+ + BrO^- + Br^-
So, if you add the acid, you increase the concentration of the Hydrogen ions, so according the Le chatelier's principle, the equilibrium will shift to the left producing Br2, thus opposing the change
emm.. from pale yellow to colorless for the titration (i think)
I don't think that was one of the choices lol... they were;
A) intermolecular forces in water are stronger than that in hexane
B) the hexane molecules can't get in between the ions
C) energy is released when the ions are hydrated
D) the sodium and chloride ions can form hydrogen bonds with the water
... so I'm guessing you went for C?
That makes sense about the acid!
And I don't mean for the titration, I mean for the one about chlorine and bromine! xD
