Which of the following is not correct corresponding to chemistry of group 14 elements ?

Options

A. Lead has no reaction with water due to formation of protective oxide layer
B. `GeX_(2)` is more stable than `GeX_(4)`
C. `PbX_(2)` is more stable than `PbX_(4)`
D. Tin on reaction with steam liberates hydrogen.

Answer

B

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 prominent 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 from Ge to Pb the inert pair effect becomes more prominent so + 4 oxidation state is becomes less stable.
So, the + 2 oxidation state of `PbX_(2)` are more stable.
