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 ?

When we move from HF to HCl , the boiling point sharply but on moving

1.	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 ?
Answer» In H-F , there is H-boiling point is high . There is no H-bonding in HCl . So the boiling point is less . On moving further to HBr and HI, the size of the molecule increases and so the van der Waals forces increase and so does the boiling point . Hence , HCl has the lowest boiling point.
