1aare i read it many books yaar....
Also if the electron is unpaired it will easily get excited as compared to the paired one's....
does dinitrogen is a colourless gas at
1) room temp
2) elevated temp
3)or both the temp
please explain

11yup buddy,
at high temp...
it can be two cases as mentioned earlier in my post....

So finally..
N2 is colorless at room temp..
and at higher temp maybe colored.. due to unpairing of electrons..

24i still don't get it.........................i am hearing this concept for the first time........
1it's not d-d dear. transition can occur b/w the bonding and anti-bonding orbitals.
24@ prateek but nitrogen is not a complex dear..........so we cant talk about d-d transition or anything like that which imparts color........
1@Anirudh....
haan kyon nahin aapka colored complex vala thread ka question solve hua....
11Arre, speak in English.......or else Sankara will not be able to understand a word in his own thread
1aare complex compnd main bhi to dimagnetic or paramagnetic ke basis pe coloured ya colorless kehte hai....on the basis of Valence Bond Theory....
24vo sab to theek hai.......par magnetic behavoiur aur colours ke relationship ka funda mere dimag mein nahin jaa raha........
33I think N2 is colorless at room temp... as if it would not be so then we should see brown brown in our room at room temp... But it is colourles...
:p
1aare unpaired or paired electrons ka pata lag jata hai.....
In case of gases in these groups the color ka pata enke dimagnetic or paramagnetic hone se pata lagta....
i.e. Odd or even number of electrons they possess....
Some exceptions r also there....
1may be becoz we cann't predict about it....
at elevated temp., below the bind dissociation enthalpy of N2 it should be colorless....
At temp., greater than bond dissociation temp. of N2 it may be colorless....
33colorless at room temp ... by MOT is cool but main prob is
at high temp is it colored?
1aare bhai,
dimagnetic gas hai....
koi unpaired electron nahin hai....
M.O.T....
33Main point is that it is colorless.. now have to explain [12]
