Question

Consider the hydrides of group 14 elements 1. CH4 2. SiH4 3. GeH4 4. SnH4 The correct sequence of thermal stability is (A) 1 < 2 < 3 < 4 (B) 1 < 2 < 4 < 3 (C) 1 > 2 > 3 > 4 (D) 1 > 2 > 4 > 3

Thermal stability of hydrides depends upon the strength of M-H bond, which decreases down the group, because of the increase in size of the 'M' atom as we go down the group. The correct sequence of thermal stability is 1 > 2 > 3 > 4.

Q. Consider the hydrides of group 14 elements

$1.$ $C H_{4}$

$2.$ $S i H_{4}$

$3.$ $G e H_{4}$

$4.$ $S n H_{4}$

The correct sequence of thermal stability is

1 < 2 < 3 < 4

1 < 2 < 4 < 3

1 > 2 > 3 > 4

1 > 2 > 4 > 3

Thermal stability of hydrides depends upon the strength of $M - H$ bond, which decreases down the group, because of the increase in size of the 'M' atom as we go down the group. The correct sequence of thermal stability is 1 > 2 > 3 > 4.
