How to rationalise the increasing bond length order in the carbonate ion, carbon monoxide, a...
Actually, in regard to bond length, you should be looking at the bond order of a single bond within the molecule. … The bond order is 2, not 4, for $\ce{CO2}$, and the bond order for the carbonate ion is somewhere between 1 and 2 due to resonance. …

Why isn't the hydroxyl group of citric acid deprotonated while the carboxyl groups are?
You are correct in saying that the carboxyl groups will have resonance structures after being deprotonated. Thus, the carboxyl groups are fairly acidic and will deprotonate in water. On the other hand …

Why is the bond dissociation energy of C-H bond higher than that of a N-H bond?
Looking at a chart of BDEs (bond dissociation energies) regarding elements bonded with hydrogen, the general trend seems to be that the BDE increases as we go to the top and to the right. …
