WebHF's high boiling point is due to hydrogen bonding which none of the other HX molecules show. The general trend is that BP increase as molecules get heavier due to more electrons and hence stronger London dispersion forces. It's HF that bucks the trend. 1 comment. WebThe boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below: T (oF) = [T (oC)] (9/5) + 32 T (oC) = 5/9 [T (oF) - 32]

WebThe low melting points for the light to middle lanthanides are thought to be due to a 4f electron contribution to the bonding, which is a maximum at cerium and decreases with increasing atomic number to about zero at erbium. The low melting points of europium and ytterbium are due to their divalency. Boiling points WebMar 22, 2016 · Here, we take a look at the boiling points of water at a variety of locations, as well as the detailed reasons for the variances.
