For questions about chemical bonds (ionic/covalent/etc.), their properties (length, energy, angle, etc.) or their relation to other molecular properties (intermolecular forces/dipole moment/etc.). Do not confuse this tag with [lewis-structures], [dipole], [intermolecules-forces], etc.

Yes, covalently bonded substances become metals in sufficiently high pressures, which vary for different compounds. Unfortunately we still don't know much about really high pressures because they are …

It's formal charge - it often doesn't mean there are full charges like in zwitterions but dative bonds are usually strongly polarised.

Electronegativity affects coordinate covalent bonds; indeed atoms which accept electrons should be "electron hungry" enough to take them. However it stems mainly from that the acceptor doesn't have co …

"Water has 2 lone pairs on O, so can it donate both (one as a pi bond) just like those compounds? If not, why?" As I posted: "It is possible for pi-donating ligands, like $\ce{NH2^{-}}$ (amide …

It seems you were on right path - for example common feldspars are solid solutions and they are mixed because they share cations, while they easily substitute one another, otherwise they exsolve - bec …

As you can see here every deoksyrybose connects with two phosphates and base and has only those three places in which they can be coonnected. Heterocyclic base is bonded with carbon atom next to oxygen atom in ring - that means it's N-glycosyl bond. You can read here more about DNA instability. …

Aromatic cations like the tropylium cation ($\ce{C7H7+}$)[1] or the cyclopropenyl cation ($\ce{C3H3+}$)[2] can coordinate to metals, creating sandwich or half-sandwich compounds. The positive charge i …

. In fact helium vdW dimer may have weakest bond even among them, and it was an achievement to observe it. …

$\ce{KHF2}$ is an ionic compound with cation $\ce{K+}$ and anion $\ce{HF2-}$, and writing $\ce{KF.HF}$ doesn't suggest covalent bond between K and F, but say that $\ce{HF2-}$ anion is adduct of F … - anion and HF molecule. The bifluoride anion is quite interesting as its bond is not only a rare symmetric hydrogen bond, but also the strongest hydrogen bond known. All hydrogen bonds have some …

I don't understand what is the big deal with bonds in acids or esters in higher oxidation states - I always thought of them as of single dipolar bonds. They shouldn't be written as double bonds. It's …
