When we move from HF to HCl , the boiling point sharply but on moving further to HBr and HI the boiling point increases . Why ? Or Out of HF, HCl , HBr and HI which has boiling point and why ?

Explanation

To understand the boiling points of the hydrogen halides (HF, HCl, HBr, and HI), we can analyze the factors affecting these boiling points step by step.

### Step 1: Identify the Compounds
We are comparing the boiling points of four hydrogen halides: HF (hydrogen fluoride), HCl (hydrogen chloride), HBr (hydrogen bromide), and HI (hydrogen iodide).

### Step 2: Consider Molecular Mass
The boiling points of substances are generally influenced by their molecular masses. As the molecular mass increases, the number of electrons in the molecule also increases, which leads to stronger London dispersion forces (a type of van der Waals force).
