The Golden Girl =D:
You've got a point there , You confused me as well LOL xD

I think you shouldn't be thinking about it TOO MUCH .. Because in both cases the CH has the highest numbers of lines closely lined up together ,so it doesn't make much of a difference ? =/


Can someone clear our doubts please (:  

Thanks =D

EDIT :[ The Exam is tomorrow so it's pretty much really Urgent =/ ]

Malak:
Ok, can you tell  me what exactly is the confusion. :S

Malak:
In Jan 2010, The single H (which is joined to the carbon with OH) is next to 5 hydrogens and so it form a mulitplet.
In june 2011, there is a single H (joined to the carbon with methyl group) and it is also next to 5 hydrogens but forms 7 peaks.

Is that your question?

First of all, my teacher always told us that when ever there are a lot of peak like these two above, it is due to the hydrogen(s) which are next to many hydrogens.
I think, in june 2011 it has 7 peaks because, don't forget, even though they hydrogens of methly group are not directly next to the single hydrogen but they do affect it and probably thats why it has 7 peaks.
In jan 2010, there is only a single H of OH which is not directly next to the 'single' hydrogen we are talking about and so it doesnt really have an impact.
------------------------------

By the way, do we have to know the mechanism between propane and iodine (the very complicated one)  :-\

jackfos92:
What is the colour of [CrCl4]- ? tetrachlorochromium 3.

The Golden Girl =D:
^ I believe it is  violet solution ..according to my chemistry knowledge *poker face*

Ladies and gentlemen can someone clear my doubt , got a test tomorrow -.-

Can someone state what a ligand exchange is and what an acid-base reaction is , what is the difference between them because I'm confused =/


Thanks (:
