To tackle this question, I’ll compare a nitrogen triple bond (N≡N) with a nitrogen double bond (N═N).
Option 1 says: higher, longer, greater. A higher bond order would be correct, but triple bonds are shorter, not longer, than double bonds, so this option misstates bond length and energy direction.
Option 2 says: lower, longer, greater. This flips the bond order to lower and also indicates a longer length, which contradicts the known fact that higher bond order strengthens and shortens the bond; so both bond order and length are misassigned here.
Option 3 says: higher, longer, smaller. While bond order being higher is correct, the length should be shorter, not longer, and bond energy for a higher bond order is typically greater, not smaller, so this option errs on both length and energy.
Option 4 says: higher, shorter, greater. This matches the established trends: a higher bond order (3 vs 2) corresponds to a shorter bond length, and a greater bond energy, reflecting stronger bonding.
Option 5 says: lower, longer, smaller. This is incorrect on all three counts relative to N≡N vs N═N: bond order should not be lower, length should not be longer, and energy should not be smaller.
Option 6 says: lower, shorter, greater. Bond order is not lower, and the order of length would be shorter only if bond order were higher; this option misstates the first two attributes despite correctly giving greater energy.
Overall, the only option that aligns with the chemical principles of bond order, bond length, and bond energy for a triple bond versus a double bond is the one that states higher bond order, shorter bond length, and greater bond energy, which is reflected in Option 4.
