Match List-I (Hydrides) with List-II (Nature)

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

Detailed Solution

$MgH_2$ – 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.
