iv. ` PbR_4` and ` PbCl_4` exists , but `PbBr_4` and Pbl_4` do not exist because of

Options

A. large size of `Br^(Θ)` and `I^((Θ)`
B. strong oxidising character of `Pb^(4+)`
C. strong reducing character of `Pb^(4+)`
D. low electronegativity of `Br^(Θ)` and `I^(Θ)`

Explanation

iv. Due to strong oxidising character of `Pb^(4+)` and weal reducing character of ` Br^(Θ)` and `I(Θ)` ions, `PbBr_4` and ` Pobl_4` do not exist .
