Question

Give any example of (i) electron deficient hydrides (ii) electron precise hydride

Answer 1

electron deficient hydrides include hydrides of group 3-a
the elements of group 3a combine with ionic hydrides and form complex hydrides
LiH+AlH3---->LiAlH4

Answer 2

HLO MATE HERE IS UR ANSWER.

❤. ELECTRON DEFICIENT COMPOUNDS OF HYDROGEN ❤

⭐. These hydrides have lesser number of electrons than required for convectional Lewis structure.

Ex:B2H6(Diborane).

⭐. Elements of group 13 will form electron deficient compounds.

❤. ELECTRON PRECISE COMPOUNDS OF HYDROGEN ❤

⭐. These hydrides have exactly the required number of electrons for conventional Lewis structures.

Ex: CH4 , C2H6.

⭐. All elements of group -14 which are tetrahedral (CH4) in geometry , form such compounds .

❤.ELECTRON RICH HYDRIDES ❤

⭐.These hydrides have excess number of electrons than required for conventional lewis structure .

Ex:NH3,H2O ,HF.

⭐. Elements of group 15-17 form such compounds.

⭐. The excess number of electrons are present as lone pairs .

Ex : NH3 has 1 -lone pair , H2O has 2-lone pairs ;HF has 3-lone pairs.
