This molecular formula is applicable for homologous series ether (-O-) a bivalent functional group and as we know ether with minimum four-C shows metamerism. $\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{O}-\mathrm{CH}_{2}-\mathrm{CH}_{3}\, \&\, \mathrm{CH}_{3}-\mathrm{O}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{3}$ are metamers.

$A \to B$ ${k_1} = {10^{15}}{e^{ - 25000/8.34\,T}}$
$C \to D$ ${k_2} = {10^{14}}{e^{ - 15000/8.34\,T}}$
Calculate the approximate temperature at which $k_1 = k_2$ ...... $K$
Reason : $[Fe(CN)_6]^{3-}$ has $+3$ oxidation state while $[Fe(CN)_6]^{4-}$ has $+2$ oxidation state.

| Period number | Group number | |
| $P$ | $2$ | $15$ |
| $Q$ | $3$ | $2$ |
Then formula of the compound formed by $P$ and $Q$ element is
