Question

State whether the given statement is true or false:

$S_4{N}_4$ is kinetically stable but endothermic with respect to its elements.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is True.

Tetrasulphur tetranitride $S_4{N}_4$ is kinetically stable but endothermic with respect to its elements.
$(\Delta H_f=460\pm 8kJ/mol)$. It is due to more stability of elementary sulphur and great bond strength of $N_2$ rather than to any inherent weakness in the $S-N$ bonds.
