Hehe.........no worries br0. :)

Just be a bit more careful next time. :D

A2 question:
does it matter wether th reagent used for the hydrolysis of an amide is said as :
(A) aq acid/alkali and reflux
or
(B) H3O+ or  H+  or  OH-?
does it differ if we're talkin bout a protein or normal amide -- cuz in th past pprs sometimes it says smthin n others ts smthin else. i ignored it at first but its gettin on my nerves now...
ny ideas?
n also they cnt decide wether they want us 2 say reflux or simply heat  >:(

No, it doesnt matters. They act. mean the same thing. ::)
Although, an equation for this reaction is simply written as (for eg:-)

Ch3CONHCH3 +H2O +H+(aq)----------> CH3COOH + CH3NH2

Have a look at this  ;) http://www.chemguide.co.uk/organicprops/aminoacids/proteinhydrolysis.html

Amides may be hydrolysed by heating under the reflux with either an acid or an alkali. :-X

thanks amelia!
