Group 15 hydrides boiling points
WebThe hydrogen halides are colourless gases at standard conditions for temperature and pressure (STP) except for hydrogen fluoride, which boils at 19 °C. Alone of the hydrogen halides, hydrogen fluoride exhibits hydrogen bonding between molecules, and therefore has the highest melting and boiling points of the HX series. WebApr 6, 2024 · Group 15 hydrides are strong reducing agents. Bond angle decreases gradually on moving down the group. This is because with increase in the atomic size of group 15 elements, the bond-pair bond-pair repulsion decreases. Group 15 hydrides have pyramidal shape and have a lone pair of electrons on the central atom.
