That is not my question :S

I know by which mechanism they react but i can't explain why?
I have read the chemguide website too and I understand it but I can't write it/explain in some easy words  ::)

Refer to the Edexcel A2 Chemistry Revision Guide. You might find what u r looking for over there.

The Golden Girl =D:
Found it (:

EDIT :

There are TWO ways for you to approach this Question

Method ONE :

Primary Haloalkane , group around it is SMALL => hence easy to attack

tertiary Haloalkane , groups around it are Bulky/big => Hence difficult to attack

Method TWO :

primary NOT Stable   [there is an intermidate formed with a C+]

tertiary => Stable , surrounded by electron donating alkyl groups

[don't know what he meant by Alkyl groups though  :-\ ]

Please, Don't forget to Include me in Your Prayers =D

Malak:
Thanks GG :D

Can anyone do this question for me :S

I don't understand why the volume is 12.5 :s

Q20 a(v)

Another doubt:

Why does diluting a weak acid increase its degree of dissociation? :S

Malak:
Plus the above, can any also make trans-esterfication clear for me :S

Trans-esterification is fine for me now
but ofcourse I have another doubt :P

(attached) How is it D :S

Thanks
