Text Solution

Verified by Experts

The correct Answer is:
D
Complex Addition compounds which do not give all their constituent ions when dissolved in water, individual identity of ions are lost, e.g., `-[Cu(NH_(3))_(4)]SO_(4),LiAlH_(4)`.
Lewis acid Electron deficient species which gain electrons while forming a bond with Lewis bases. e.g., `-B_(2)H_(6)`.
Interstitial metal hydrides f-block hydrides are non-stoichiometric eg, `LaH_(n)` etc, where chemical composition is variable e.g., `-LaH_(2.87),X_(b)H_(2.5)` etc.
Intermediate hydride Polymeric in nature e.g., `BeH_(2)`.
Covalent hydride Bond forms by sharing of electron. e.g., `AsH_(3)`.
