Per NCERT Table 5.3(b), the bond enthalpy of N≡N triple bond is which value — among the highest known for diatomics?
A741 kJ/mol
B435 kJ/mol
C498 kJ/mol
D946 kJ/mol
Answer & Solution
Correct answer: D. 946 kJ/mol
Per NCERT Table 5.3(b), N≡N = 946 kJ/mol (very strong; reason N₂ is inert). O=O 498, C=O 741, H-H 435.
