Main Question or Discussion Point

Does CN neutral exist?
if it will their will be a triple bond but their will be 1 single electron left in the carbon atom
now if answer is yes i am all good but if no then why can't 1 unpaired electron remain unbonded?why has it always got to be a "pair" of electrons?

No.
Free -CN radicals do exists, but as said, they are free radicals and have a single electron on them. Giving them an overall charge.

"There". Not "their".

No.
I'm rather sure that I've seen spectral data for it in Huber Herzberg, so this would most certainly mean that it does exist.

Note that there are very few molecules which cannot exist under some conditions (low temperature, pressure, etc), at least for a short time. Even molecules with the most outrageous bonding patterns typically have minima in their potential energy surfaces. Compared to that, the CN radical seems rather harmless.
