$C{H_3}C{H_2}I + KO{H_{(aq)}} \to C{H_3}C{H_2}OH + KI$
is classified as :
| Element | $IE_1$ | $IE_2$ | $IE_3$ |
| $P$ | $495.8$ | $4562$ | $6910$ |
| $Q$ | $737.7$ | $1451$ | $7733$ |
| $R$ | $577.5$ | $1817$ | $2745$ |
Then incorrect option is

$M + L \rightleftharpoons ML$
$ML + L \rightleftharpoons M{L_2}$
are $4$ and $3$. Hence, overall stability constant for
$M + 2L \rightleftharpoons M{L_2}$ is
