Vedclass · Answer

(D) Hydrides are classified as electron-deficient,electron-precise,or electron-rich. $CH_4$ is an electron-precise hydride because it has the exact number of electrons required to form its covalent bonds ($8$ electrons in the valence shell of carbon). Electron-precise hydrides are generally neutral in nature. $PH_3$ is an electron-rich hydride (contains lone pairs),$NaBH_4$ is an ionic/complex hydride,and $HBr$ is an acidic hydride.
