Edexcel CHEMISTRY DOUBTS!!!!

[The Golden Girl =D]

Relina , I don't know if I'll be of much help but here I go =]

I think it's because NH3 is a WEAK Base.

A : HCl and NaOH  => since it's STRONG Acid then it has HIGH concentration of Hydrogen Ions.
B : HCl and NaCl => since it's STRONG Acid and hence has  HIGH concentration of Hydrogen Ions.
C : NH₃ and it's salt  => It's a WEAK Base so most likely to have LOWEST concentration of Hydrogen Ions!
D : CH₃COOH  and it's salt => has Low Hydrogen Ions since it's a WEAK Acid.

Bases have plenty of  OH^- Ions where as Acids have plenty of   H⁺ Ions. In other words , the Base has fewer [H⁺] than the Weak Acid =D

I just tried to make sense out of it so that I make myself understand it so I'm not 100 % sure but that's how I got it =]

I hope I helped

I love the way you convince me 
thnxs alot

guys here is my question and plz do explain it as I'm totally confused    
 that's  a NMR question
why do we get 4 peaks  only for that ''C₆H₅CH₂CH₂CH₃ ?


if you are going to answer because peak for ch2 ,peak for second ch2 , peak for ch3 ,peak for c6h5

then I don't understant why are the five hydrogen atoms in benzene ring are the same ?

 

as it's opposing this example of 3 peaks for product of cyclohexene and bromine

[NotAbod]

which unit is it? from which year?

[~ Miss Relina ~]

which unit is it? from which year?

 I dunno it's from examwizard 

did you get it 

[NotAbod]

what 4 peaks?
Is it related to the mass spectrometer?

Sorry, don't know what's that, its not unit 1.

ooopsss

Not sure if i understood your question exactly but will try to explain.

Peaks appear on NMR cause of the different environments of H

Not sure about the benzene part (structure) but i guess because the five H atoms are in the same environment i.e. next to same groups

''C6H5CH2CH2CH"
In the case above, the last CH is next to 2 H so it will have its own peak (triplet)
the CH2 has one H on one side and 2H on the other so it has different environment and therefore a different peak
the last CH2 has C6H5 next to it and CH2 next to it so again a different environment

Hope you get it..

here can you explain this also plz

I hope this diagram explains it.

The CH₃ is next to a CH2 (according to the diagram it's blue in the sketch I did) and hence n+1  means that it's a Triplet.

the last CH is next to 2 H so it will have its own peak (n+1 => triplet)

so triplet and triplet , same environment and hence it's considered as One peak ?

this is PURE ta5bees I guess , but well this might be a possibility who knows

[ Don't ask me how I got it since ana mu5i darab min 2asasu fa I don't think I'll remember lol ]

ok ta5bees msh wa7esh

bas I need to get that bold line

[The Golden Girl =D]

Okay here is a diagram cuz there is no way to explain but this way =]

In the attached diagram. the CH₂ is attached to TWO CH₃. SAME Hydrogen Environment and hence considered as ONE Peak.

I took this idea and tried to Fit it in the one you were confused about.

This is all I can come up with I hope you get it =]
