Why does nitrogen show poor tendency towards catenation?

Why does nitrogen show poor tendency towards catenation? Correct Answer The N – N single bond is weaker and unstable

The N – N single bond is highly weak and unstable due to high magnitude of inter-electronic repulsions of non-bonding electrons which in turn is caused by the single bond’s small bond length. As a result the catenation tendency becomes weaker due to the mentioned factors leading to instability.

In order to prepare Lithium nitride, air is passed gently over a reactor. Suppose that Nitrogen diffuse to a length 5cm before getting reacted with Lithium. Nitrogen reacts with lithium quickly so that partial pressure of Nitrogen at that point is 0. Reactor is a cylinder of length 10cm and diameter 2cm. Assume air to be a mixture of Nitrogen and Oxygen only. The temperature is 298K and total pressure 1atm. Diffusivity of N2 in O2 is 2*10-5m2/s. Calculate the Molar flux (mol/m2.s) of N2 at a distance of 2.5cm from the top with respect to an observer moving with twice the mass average velocity a direction towards the liquid surface. (R=8.205*10-5m3atmK-1mol-1). Assume z=0 at the top of the reactor.
Ten boys B1, B2, B3, B4, B5, B6, B7, B8, B9, and B10 are sitting in a row facing towards the north (not necessarily in the same order). Only four boys are towards the left of B9. B6 is fourth to the right of B9. No boys are towards the left of B2. B5 is to the immediate right of B3. B4 is not towards the right of B6 and not towards the left of B9. B1 is second to the left of B7. B7 is third to the right of B2. Only two boys are sitting towards the right of B5. If B5 is to the immediate left of B6, then how many boys are sitting between B10 and B8?
