Question
The various types of hydrides and examples of each type are given below :
|
Hydride type |
|
Compound |
| a. |
Electron deficient |
1. |
$$LiH$$ |
| b. |
Saline |
2. |
$$C{H_4}$$ |
| c. |
Electron-precise |
3. |
$$N{H_3}$$ |
| d. |
Interstitial |
4. |
$${B_2}{H_6}$$ |
| e. |
Electron rich |
5. |
$$CrH$$ |
Choose the correct matching from the codes given below :
A.
a - 2, b - 4, c - 5, d - 3, e - 1
B.
a - 4, b - 1, c - 2, d - 5, e - 3
C.
a - 4, b - 3, c - 5, d - 2, e - 1
D.
a - 5, b - 3, c - 4, d - 2, e - 1
Answer :
a - 4, b - 1, c - 2, d - 5, e - 3
Solution :
$$\eqalign{
& {\text{Electron}}\,\,{\text{deficient}} - {B_2}{H_6} \cr
& {\text{Saline}} - LiH \cr
& {\text{Electron precise}} - C{H_4} \cr
& {\text{Interstitial}} - CrH \cr
& {\text{Electron}}\,\,{\text{rich}} - N{H_3} \cr} $$
