In which state does the bifluoride anion exist?

Statement 1. The $\ce{HF2-}$ ions exist in solid state and also in liquid state but not in aqueous state. Statement 2. The magnitude of hydrogen bonding between $\ce{HF}$ is weaker than that ...

Does hydrogen peroxide exhibit intramolecular hydrogen bonding interactions?

We know that intermolecular hydrogen bonding is seen in hydrogen peroxide $(\ce{H2O2})$. But is intramolecular H-bonding, i.e. hydrogen bond between an oxygen atom and a hydrogen atom attached to the ...
