1.	Why does nitrogen show poor tendency towards catenation?(a) N atom can form multiple pπ – pπ bonds(b) Octet of N2 is complete unlike carbon(c) The N ≡ N is unreactive at room temperature(d) The N – N single bond is weaker and unstableThe question was posed to me by my school teacher while I was bunking the class.Enquiry is from P-Block topic in chapter P-Block Elements of Chemistry – Class 12
Answer» The correct option is (d) The N – N single bond is weaker and unstable Explanation: 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.
