Question

classify the given hydrides as electron deficeint, electron reach, interstitial or ionic H2O,B2H6,NAH and LaH3
​

Answer 1

The given hydrides are of the following types-

H₂O- Electron rich hydride

• As the oxygen atom has 2 lone pairs of electrons, it is an example of an electron-rich hydride.

B₂H₆ - Electron deficient hydride

• It is called diborane and acts as a Lewis acid.

NaH - Ionic hydride

• The elements of s-block react with hydrogen to form ionic hydrides.

LaH₃ - Interstitial hydride

• As the elements of d and f block react with hydrogen to form interstitial hydrides.
