Question

Match List - I with List - II.

List I(Hydrides)		List II (Nature)
a	$MgH _{2}$	i	Electron precise
b	$GeH _{4}$	ii	Electron deficient
c	$B _{2} H _{6}$	iii	Electron rich
d	$HF$	iv	Ionic

Choose the correct answer from the options given below:

• A. (a) - (ii), (b) - (iii), (c) - (iv), (d) - (i)
• B. (a) - (iv), (b) - (i), (c) - (ii), (d) - (iii)
• C. (a) - (iii), (b) - (i), (c) - (ii), (d) - (iv)
• D. (a) - (i), (b) - (ii), (c) - (iv), (d) - (iii)

Answer 1

Answer: (B)

Electron deficient hydride $\rightarrow$ Less than $8 e^{-}\left( B _{2} H _{6}\right)$
Electron precise hydride $\rightarrow$ having $8 e^{-}$without l.p. $\left( GeH _{4}\right)$
Electron rich hydride $\rightarrow$ having $8 e^{-}$with l.p. $(HF)$
