Vedclass · Answer

(C) Hydrides are classified based on the number of electrons and bonds present in the molecule.$1$. Electron-deficient hydrides have fewer electrons than required for bonding (e.g.,$B_2H_6$).$2$. Electron-precise hydrides have the exact number of electrons required to form covalent bonds,typically found in group $14$ elements (e.g.,$CH_4, SiH_4, GeH_4$).$3$. Electron-rich hydrides have excess electrons as lone pairs,typically found in groups $15, 16,$ and $17$ (e.g.,$NH_3, H_2O, HF$).Therefore,$SiH_4$ is an electron-precise hydride.

Which of the following hydrides is an "electron-precise" type?
