When N₂ is converted into N₂⁺, the dissociation energy of the N–N bond ______, and when O₂ is converted into O₂⁺, the dissociation energy of the O–O bond ______.

Question

Accepted Answer

decreases, increases. N2 -> N2+ removes a bonding electron, dropping bond order 3 -> 2.5, so the bond energy DECREASES. O2 -> O2+ removes an antibonding (pi*) electron, raising bond order 2 -> 2.5, so it INCREASES. Hence 'decreases, increases'.

When N₂ is converted into N₂⁺, the dissociation energy of the N–N bond , and when O₂ is converted into O₂⁺, the dissociation energy of the O–O bond .
