Which of the following is not correct corresponding to chemistry of group 14 elements ?
- A Lead has no reaction with water due to formation of protective oxide layer
- B \(\mathrm{GeX}_2\) is more stable than \(\mathrm{GeX}_4\)
- C \(\mathrm{PbX}_2\) is more stable than \(\mathrm{PbX}_4\)
- D Tin on reaction with steam liberates hydrogen.
Answer & Solution
Correct Answer
(B) \(\mathrm{GeX}_2\) is more stable than \(\mathrm{GeX}_4\)
Step-by-step Solution
Detailed explanation
Ge is the elements of group 14 (carbon family). In which Ge shows oxidation state +2 and +4 but +4 for Ge is more prominant while, due to sheilding of \(s\)-electrons by intervening \(d\) and \(f\)-electrons as the number of \(d\) and \(f\) electrons increases down the group…
