Why does hf have a high boiling point than hcl? a) The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. … e) The atomic weight for CL is greater than for F, so HF will have a higher boiling temperature.
Why does HF have such a high boiling point? Hydrogen bonding is the strongest intermolecular force. Due to strong intermolecular forces, the molecules of HF will be tightly packed in a lattice. Thus, HF will have the highest boiling point since the boiling point of a system depends upon the intermolecular interactions.
Why is the boiling point of HCl lowest while that of HF highest? The boiling point of covalent compounds(HF, HCl, HBr, HI) increases with an increase in their molecular weight due to an increase in Van Der Waal’s forces of attraction among molecules. … HCl has the least boiling point due to the small dispersion intermolecular forces. HCl < HBr < HI < HF.
Why does HF have a higher boiling point than HCl HBr and HI? We can conclude, the order of boiling point followed is HF > HI > HBr > HCl. … The reason is the presence of strong hydrogen bonding in the HF, as hydrogen intermolecular interactions are greater than the van der Waals forces. So, HF has a higher boiling point than the HI.

Can you get boiling water on a plane?
A: That is a very good question. The reason why water boils under 100 degrees Centigrade or 100 degrees Celsius is because commercial airplanes are not pressurized to air pressure at sea level, but to about 8,000 feet or about 2,400 meters. … At that effective altitude, water will boil at around 93.6 degrees Centigrade.
Can we boil milk in microwave?

What is the relationship between hydrogen bonding and boiling point?
Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which don’t have an an -O-H or an -N-H group. The hydrogen bonding makes the molecules “stickier,” such that more heat (energy) is required to separate them.
