Which of the following compounds is the least stable? A) CH₄ B) SnH₄ C) SiH₄ D) GeH₄ E) PbH₄

Question

Quizplus · Accepted Answer

PbH4 (lead hydride) is the least stable among the given hydrides. This is because as we move down the group in the periodic table, the bond strength between the metal and hydrogen decreases due to the increasing size of the metal atom. Lead, being at the bottom of the group, forms the weakest bond with hydrogen, making PbH4 the least stable of the options provided.
