it should be +2 as Nitrogen is more electronegative than Carbon,it will show negative oxidation number of -3,now hydrogen always shows +1,so oxid. number of C should be +2. rate me if satisfied

You can never solve a problem on the level on which it was created.
When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity
Purpose of solving a problem is not simply to get the answer(the answer is only an evidence) but to develop your thinking ability |

is it HCN or HNC???
in HNC, ox no of carbon will be ZERO.
coz H-N=->C.

N is more electronegative among all of given elements,so it will have negative ON,-3 is more stable

umang in HNC, there is one double and one coordinate bond between N and C. thus ON, will be +2 (due to double bond) - 2(due to coordinate bond) = ZERO.
plz rate if helpful.

Hiii
well the answer is +2
it cud have been different as H-N = (and a cordinate bond) C
but here contribution of cord. bond is neglected ocz N is very much electro-ive than C
so Oxdn no. of N remains -3
and H is +1
so
1-3+x = 0 , x = +2
it remains + 2 in HCN also
coz there it has H-C =_N
hence the answer :) :)

SO for formal charge we use that formula, while for ON we directly compare EN. is this the difference??

arey it has to do with chemical bonding its in jst case of Carbon...u cannot calculate the oxdn no. directly

Hey !
I read in a book that in a coordinate bond, if donor atom is more electro-ve than acceptor, then coordinate bond is treated as simple covalent bond
acc. to this, i get a different answer!
