This is true in all four groups in figure 4; the only …
WebAnswer: Just like its next door neighbour, water, it’s because of hydrogen bonding. However, as water has two hydrogen atoms per molecule and two lone pairs, it is able to link together far more molecules than ammonia that has a 3:1 hydrogen/lone pair ratio, hence water’s much higher boiling poin... WebWhich has the lowest boiling point in the hydrides of group 15 elements? PH3 has the lowest boiling point. Boiling point depends on the strength of intermolecular forces. As we move down Group 15, the elements increase in polarizability, and thus their London Dispersion Forces increase.
