Why does potassium bifluoride exist whereas bichloride does not?

Why does the reaction \eqref{rxn:R1Q} take place, but the reaction \eqref{rxn:R2Q} does not? $$ \begin{align} \ce{HF(aq) + KF(aq) &-> KHF2(aq)}\label{rxn:R1Q}\tag{R1} \\ \ce{HCl(aq) + KCl(aq) &...

Hydrogen donor without hydrogen acceptor?

Is there a molecule that can donate a hydrogen to a hydrogen bond but not accept one? It would seem that since the donated hydrogen needs to be bonded to an electronegative atom, that electronegative ...

Is Hydrogen Bonding a Type of Dipole Dipole Interaction?

I understand that dipole dipole forces is due to the attraction of the different partials charges of atoms in different molecules due to their different electro-negativities. For hydrogen bonding, ...

Hydrogen bonding in chloral hydrate

Normally, chlorine doesn't form hydrogen bonds because despite its electronegativity, the size of the atom is such that its electron density is too low to form hydrogen bonds. However, chlorine forms ...

Hydrogen bonding of chlorine [duplicate]

Even though nitrogen is less electronegative than chlorine according to Pauling scale bit why don't it form hydrogen bonding as effective as of nitrogen ? ( Electronegativity valve of N =3.0,Cl=3.2)

Hydrogen bonds - why not in HCl? [duplicate]

In a textbook1, I found the following clear definition of hydrogen bonds: The strongest secondary bonding type, the hydrogen bond, is a special case of polar molecule bonding. It occurs between ...

electronegativity and hydrogen bonding [duplicate]

I have a basic idea why, but can someone just confirm, why chlorine isn't able to hydrogen bond despite the fact that it has the same electronegativity value as nitrogen.

Can chlorine form hydrogen bonds? [duplicate]

My question is simple, If chlorine ($\ce{_17Cl^35^.^5}$) and nitrogen ($\ce{_7N^14}$) have similar values of electronegativity, and chlorine has way more lone pairs than nitrogen, what prevents it ...

Does oxygen gas form hydrogen bonds?

I learned that hydrogen bonding is formed from a 'sandwich' of hydrogen and either oxygen, nitrogen, or fluorine where nitrogen, fluorine, or oxygen is the bread. Will oxygen gas and water form ...

Why can't chlorine atoms form hydrogen bonds? [duplicate]

Why can't chlorine atoms form hydrogen bonds even though they have very similar electronegativity to nitrogen, which can? Electronegativities are as follows: $\ce{Cl} - 3.16$ $\ce{N} - 3.04$ Is it ...
