c. The boiling point of HF is much higher than those of the other hydrogen halides.

Hello everyone. Today, we have a fine problem explain why hydrochloric acid has a lower boiling point than Hydrofluoric acid with a boiling point. The boiling point of a substance is influenced. So the boiling point is influenced by bonds or forces known as intermolecular forces abbreviated as IMF and these are present between molecules. Now, Hydrofluoric acid as a special kind of bond known as a hydrogen bond. And these are extremely strong strong bonds and they're also due to the high electronegativity of fluorine. So fluorine is partially negative and hydrogen is partially positive due to the electron withdrawing. Now, if we look at hydrochloric acid, this bond is not a hydrogen bond instead, this is a dipole dipole bond. And while that is strong, it is not as strong as a hydrogen bond. And so, while chlorine is more electron than hydrogen and is partially positive as a result, this dipole dipole bond is weaker than a hydrogen bond. And so with that, we have solved the problem overall, I hope this helped. And until next time
