Question:medium
Which hydride amongst the following has the least boiling point?
Which hydride amongst the following has the least boiling point?
Show Hint
In hydride groups ($15, 16, 17$), the first member usually has an anomalously high boiling point due to hydrogen bonding, making the second member (like PH$_3$ or H$_2$S) the one with the lowest boiling point.
