MARKS App · Accepted Answer

B 2 H 6 , known as diborane, is an example of an electron-deficient hydride. HF , or hydrogen fluoride, is an example of an electron-rich hydride. Electron-rich hydrides are molecules that contain more electrons than what would be expected based on the normal valence electron count for the atoms involved. CH 4 is electrons precise hydride since, there are exact number of electrons to form normal covalent bonds for completing octet. MgH 2 is salline hydride, as this is the hydride that formed when hydrogen reacts with s-Block elements.
