Answer 2

Answer:

Electron deficient compounds. Hydrides of group 13 (i.e. BH3, AlH3etc.) have lesser electrons to form normal covalent bonds and hence are called electron deficient hydrides. To make up this deficiency, these hydrides generally exist in polymeric forms such as B2H6, B4H10, (AlH3)n etc. ... (iii) Electron rich compounds

Electron precise: The type of hydrides that have the exact number of electrons to form a covalent bond are called electron precise. These types of compounds are usually formed by group 14 elements. The compounds usually have a tetrahedral shape. Example CH4, SiH4, etc.

Electron rich: The type of hydrides which have more number of electrons than required for bonding are called electron-rich hydrides. The excess number of electrons are mainly the lone pair of electrons on the central atom. These types of compounds are usually formed by groups 15, 16 and 17 elements.
