Me? My paper went awesome. I completed it in 30 minutes or so.. and went through the whole paper again.. Apart from 3 marks of the 1st question and 2 marks for that Cl2 to ICl increase(Doubtful in both those) .. My paper went good and all answers have been verified.

Insha Allah hoping to get marks in the 50s :)
Cl2 and BrCl has no dipole and Icl has i dipole cause en value of C and I the same and CHCl3 has a dipole :cool: daredevil MustafaMotani ur views?

BrCl is dipole.. but its just not stong dipole as compared to ICl .. since electronegativity decreases down the groUp ... Iodine least dipole ..Chlorine most dipole ...and thus resulting charge would be highre

How much would my answer get ..listed above? it was of 2 marks.

well i am not sure cause dipole would have caused higher increase in bp/mp i guess . Cl2 has least en value difference we are not talking about dipoles but en value diff

higher the en difference stronger the dipole-dipole charge

oh thank god, *high five* :D i think i missed a couple marks though, O.N. of N in nh3 is supposed to be -3, and i wrote +3!! also i messed up the pressure of contact process (should be 100 kPa, i wrote 100 atm) *facepalm*
it could be 1 to 2 atm -_-

i wrote wat mustafa wrote.... about the greater electronegaivity differnce ... the greatest electronegativity within the 3 molecules was in ICl thus it ws the answer
no the question before it in which we had to describe change in boiling points . that one is ICl it was aparent to any one who knew that an object with greater boiling point has greter force

Yea -,- I wrote 2atm, 450C and Vandium V Oxide catalyst.. btw 1atm is 100kPa :p

oh how are you preparing for computers? have you started preparations?
started now i am revising chapters today and doing past papers tommorow and then rerevising next day :)
