(2019 Main, 11 Jan II)

(a) $A l H_{3}$

(b) $B_{2} H_{6}$

(d) $G a H_{3}$

Show Answer

Answer:

Correct Answer: 10. (d)

Solution:

$G a H_{3}, A l H_{3}$ and $B_{2} H_{6}$ are the hydrides of group-13 $(n s^{2} n p^{1})$ , whereas $S i H_{4}$ is an hydride of group 14.

So, $B_{2} H_{6}, A l H_{3}$ and $G a H_{3}$ are electron deficient hydrides. But, $S i H_{4}$ is an electron precise hydride of group-14 $(n s^{2} n p^{2})$ , i.e. these hydrides can have the required number of electrons to write their conventional Lewis structures.
