It doesn't have hydrogen bonding, which results in less intermolecular attractions and therefore a lower boiling point.
The formula of hydrazine is N2H4. It looks like this HH-N-N-HH The answer really is that, for a molecule that size, it is a very high boiling point. A molecule with a similar size and mass is ethane, which is a gas at room temperature. The reason it has such a high boiling and melting point is that when nitrogen and hydrogen bond, the nitrogen has a greater attraction to the electrons that they share, so the negatively charged electrons are closer to the nitrogen. This makes the nitrogen slightly negative, and the hydrogen slightly positive. When another hydrazine molecule is near, the negative Nitrogen on one molecule is attracted to the positive hydrogen on another molecule. This makes them harder to separate by boiling, and so it has a higher boiling point.
Helium has a low boiling point because there are no inter-particular forces to attract it to other helium atoms. It does not have enough electrons to have random dispersion forces as larger atoms do.
In summary, substances are liquid or solid at room temperature ie have a high boiling point, because there are forces between the atoms or particles. The forces can be:
Weak intermolecular force of attraction. Little amount of energy is needed to separate the molecules. Therefore hydrogen has a low boiling point.
does hydrogen have a low or high boiling point
Because it is extremely smelly and nasty. If you boiled it at an even higher temperature then the smell would get around the neighbourhood very much.
ethene- van der waals forces
hydrazine - hydrogen bonds
hydrogen bonds are stronger
it is due a weak covalend bond formation
due to weak intermolecular forces
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
yes they do have a low boiling point
van der waals force
because it does not have a high boiling point.
Liquid Nitrogen, liquid oxygen etc are low boiling point liquids
no..ethers are always low in boiling point than alcohol due to alcohols hydrogen bonds
I think , when we add surfactant in a solution , surface tension of that solution become low. boiling point of any solution just depend on force of attraction between molecules as much as attraction is high boiling point is high. as we know surface tension of solution became low means force of attraction between the molecules will be low , so in this way boiling point of that solution will become low......

The liquid with low boiling point.
yes they do have a low boiling point
They Have a low boiling point
high boiling point low melting point
Low boiling point of -268.93 °C
van der waals force
No, 68 is a low boiling point.
because it does not have a high boiling point.
Low boiling point liquids are flammable.
