cyclobutane
NaI has the lowest boiling point at standard pressure because it is a molecular compound with weaker intermolecular forces compared to the other compounds listed, which are all ionic compounds. Ionic compounds generally have higher boiling points due to stronger electrostatic interactions between ions.
The lowest boiling point among CuCl2, HF, and MgCl2 is HF. This is because HF is a molecular compound with weaker intermolecular forces compared to the other two, which are ionic compounds with stronger electrostatic interactions between ions.
Oxygen has the lowest boiling point of these. It is far below the boiling points of the others.
Gasoline is the petroleum refinery product has lowest boiling point.
Empirical formula (lowest whole number) for C4H8 is CH2, obtained by dividing by 4.
Helium has the lowest boiling point of any known substance, at -268.9 degrees Celsius.
The alkane with the lowest boiling point among all alkanes is methane.
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
The top of an oil fractionating column is where the lighter hydrocarbon fractions, such as gases and light liquids, are collected and removed from the column. This process separates the different components of crude oil based on their boiling points.
Pentene
Helium has the lowest boiling point of not just the noble gasses, but of any known substance.
Helium melting point: -272,2 0C Rhenium boiling point: 5 596 0C
