(b) They give ninhydrin test
(c) On reacting with nitrous acid give off ${N_2}$
$CS_2 + 3O_2 \to 2SO_2 + CO_2$
| $\Delta H \,(kJ/mol)$ | |
| $\frac 12 A \rightarrow B$ | $+150$ |
| $3B \rightarrow 2C + D$ | $-125$ |
| $E + A \rightarrow 2D$ | $+350$ |
For $B + D \rightarrow E + 2C, \Delta H$ will be ............. $\mathrm{kJ/mol}$
