Amino Acid chains. C=O And N-H. Hydrogen bonds between O and N. And guess what! The O isn't directly attached to H!




You're very right here. Any other day, I'd have said you were right and Hydrogen Bonds exist b/w CH3F and H2O. BUT, not today. Not while you're still an A Level student. Not till you're done with P4 tomorrow. The A Level syllabus is limited to, rather stupidly, NOF bonded DIRECTLY to H with one exception of aa's in Applications. So, as far as questions go, you're not gonna use any logic. You're not gonna use your brain. You're going to see if N O or F is directly attached to H or not.

And they call themselves CIE... :D

For R-COCl, Ar-Cl and RCl, which is easier to hydrolyse and why? I know Ar-Cl is the most difficult due to interaction between lone electron pairs of Cl and delocalised pi electrons of the benzene ring. But, what about the other two?

For R-COCl it is the easiest as the carbon atom attached to Cl is Extremely +ve beascause of the polar C--O bond and C--CL bond, both Cl and O are highly electronegative elements
For RCL only one electronegative element and there are no other interactions with it

So R-COCl is easier to hydrolyse right?
Thanks. :)

It's official. I'm screwed. I have forgotten everything. The one subject I had hopes of getting an A* in now see's me trying to just reach to an A, and even that seems like a huge task. FML.

Good luck, everyone!
you wont ,trust me you have that feeling before an exam and you do good in it .I have the same feeling too.

Do not worry! You are not alone :D! Nah... just kidding, we will do fine! Usually the best chemists struggle the most, simply because they know the most!

The fact that my exam is in 2 hours or so and I don't know applications speaks volumes
