Question

Match List-I with List-II

List- I	List-II
(Hydrides)	(Nature)
(a) MgH2	(i) Electron precise
(b) GeH	(ii) Electron deficient
(c) B2H	(iii) Electron rich
(d) HF	(iv) Ionic

Choose the correct answer from the options given below:

(1) (a) (iii), (b)(i), (c) (ii), (d) (iv)

(2) (a)-(i), (b) (ii), (c) - (iv), (d)- (iii)

(3) (a)-(ii), (b) (iii), (c) - (iv), (d) (i)

(4) (a) (iv), (b) (i), (c) (ii), (d) (iii)

Answer 1

(4) (a) (iv), (b) (i), (c) (ii), (d) (iii)

Electron deficient hydride → Less than 8e (B₂H₆) 

Electron precise hydride → having 8e^- without I.p. (GeH₄) 

Electron rich hydride → having 8e^- with 1.p. (HF)
