@Mystic I had never understood the question :p
What is the oxidation state of carbon in cyanogen?
I think it is +4
Nitrogen pulls 3
CN as a whole is more electronegative than carbon
so the CN pulls another electron?
but it should be symmetric?
NC-CN
if one CN takes one electron
then the other one won't have it
but both the CNs are same
I still can't get my admit card. @Mystic did you get it?

@YashasSamaga That is not the correct way to think about it.

@MadhuchhandaMandal yeah it was , But I was able to complete it
do primary valencies are always negative ions ?

My limited knowledge suggests that they need not always negative ions
Because the total ON of the coordination sphere may be negative
(I think so, not sure)
Find the value of : sin-1(2x-√(1-x^2))
Sorry that was wrong
Find the value of : sin-1(2X x √(1- X^2))
given | x | <1
