Bond Stability of Carbon with Nitrogen Family :
C - N > C - P > C-As > C - Sb.
Understanding :
1) We know that, due to higher difference between Electronegativity between C and Nitrogen, A C -N bond is strongly polarised towards Nitrogen.
As,Electronegativuty down the group decreases.
So, Polarisation of Carbon will be less towards other element down the group.
So, Bond -Stabilty decreases down the group.
2) Overlapping of similar size atomic orbital is higher as compare to different size.
Since, Carbon size is pretty much similar to Nitrogen.
Whereas down the group, Size increases and difference increases.
=> Overlapping of atomic orbitals becomes low.
So, Bond stability decreases down the group.

Greater the difference in electronegativity of the 2 atoms making a bond, higher is the stability of the bond.
Also, lesser the difference in the size of the orbitals of the atoms forming the bond, stronger is the bond.
Going by this, the C---N would be the strongest of all the bonds since they have the largest difference in electronegativity and the smallest difference in the size of orbitals.
