WebIn H2O strong hydrogen bonding is present which makes it a liquid. In H2S and H2Se weak intermolecular forces are present. Therefore H2S and H2Se are gases at room temperature. The boiling point of HBr is higher than HCl It is due to the bigger size of bromine than chlorine. WebWhich liquid has the highest boiling point: 1. HI 2. HF 3. HBr 4. HCl Correct Answer: 2. Comments to the instructor: The strongest intermolecular force for HF is the hydrogen-bonding interaction. This is a stronger force than the dipole-dipole interactions between HI, HBr and HCl. Which solid has the lowest melting point: 1. I2 2. Cl2 3. F2 4. Br2
