Q46. Single bond is not formed by two atoms of:
(a) P - P
(b) N - N
(c) As - As
(d) Sb - Sb

Q: What is the correct answer for CUET UG Chemistry Q46?

The correct answer is B. This question is phrased in a way that suggests a bond that 'does not form'. However, N-N single bonds are common (e.g., in hydrazine, N2H4). All elements in Group 15 (N, P, As, Sb) form single bonds with themselves (e.g., N2H4, P4, chains of As and Sb). The passage emphasizes nitrogen's ability to form pπ-pπ multiple bonds. While N-N single bonds are weaker than P-P single bonds due to lone pair-

This question is phrased in a way that suggests a bond that 'does not form'. However, N-N single bonds are common (e.g., in hydrazine, N2H4). All elements in Group 15 (N, P, As, Sb) form single bonds with themselves (e.g., N2H4, P4, chains of As and Sb). The passage emphasizes nitrogen's ability to form pπ-pπ multiple bonds. While N-N single bonds are weaker than P-P single bonds due to lone pair-lone pair repulsion, they are definitely formed.Given the provided solution key, (b) N-N is the answer. This could be interpreted as 'N-N single bonds are exceptionally weak/unstable compared to multiple bonds or other Group 15 single bonds', or that the question has a nuance or an error in its literal interpretation.
