Question

Match the following (Types of Hydrides vs. Group Elements):

Type	Group Elements
A. Electron-deficient	I. Group 13
B. Electron-rich	II. Group 15
C. Electron-precise	III. Group 14
D. Interstitial	IV. Group 4 (d-block metals)

• A. A – I, B – III, C – II, D – IV
• B. A – III, B – II, C – IV, D – I
• C. A – III, B – IV, C – II, D – I
• D. A – IV, B – I, C – V, D – III

Hint:

Match hydride types with their characteristic groups: Group 13 – deficient, Group 15 – rich, Group 14 – precise.

Answer 1

The Correct Option is A

- Electron-deficient hydrides: typically group 13 elements like B and Al (e.g., B$_2$H$_6$)
- Electron-rich hydrides: group 15 elements like N and P with lone pairs (e.g., NH$_3$)
- Electron-precise hydrides: group 14 elements (e.g., CH$_4$, SiH$_4$)
- Interstitial hydrides: transition metals (e.g., TiH$_x$, Group 4)
