Match List-I (Hydrides) with List-II (Nature)
Pick the matching item from Column II for each row.
Column I
- A. $MgH_2$
- B. $GeH_4$
- C. $B_2H_6$
- D. HF
Column II
- I. Electron precise
- II. Electron deficient
- III. Electron rich
- IV. Ionic
Correct answer: A → IV, B → I, C → II, D → III
$MgH_2$ – ionic (saline) hydride $GeH_4$ – electron precise (8 electrons, no lone pair) $B_2H_6$ – electron deficient (less than 8 electrons) HF – electron rich (8 electrons with lone pairs) Correct match: A-IV, B-I, C-II, D-III.
