Question

Whata are metallic hydrides . how do they differ from molecular hydrides? ?

Answer 1

Hello Dear,

Here is your answer, 

Metallic Hydrides ⇒ 
Metal hydrides are the compound which are formed by metal and hydrogen , So Basically these are the compound which reacts transition element to form hydrogen.

Examples-→
_________________________

i)  CaH₂ - Calcium Hydride 
iii) LiBH₄- Lithium BoroHydride
________________________

Molecular Hydrides - 

Molecular or covalent hydrides formed by the combination of an element which is having comparable higher electronegativity.

Molecular hydrides are liquid or gases that have low melting & boiling point.

Examples→
______________________

i) H₂O
ii) B₂H₆
iii) PH₃
iv)H₂O
______________________


←←Difference B/w Metal & Molecular Hydrides→→

1)- Metal hydrides having high electrical Conductivity , While Molecular hydirde have Low electrical conductivity.

2)- Metal Hydride having High Thermal conductivity , Molecular Hydride have low thermal conductivity

3)- Metallic hydride are found in solid state while Molecular hydride are soft & volatile in Nature. 

Hope it Helps.

Have a Marvelous Day.
