Given below are two statements:
Statement $I$: The increasing order of boiling point of hydrogen halides is $HCl < HBr < HI < HF$
Statement $II$: The increasing order of melting point of hydrogen halides is $HCl < HBr < HF < HI$
In the light of the above statements, choose the correct answer from the options given below

Consider the following reaction:
$Cl_{2(g)} + H_2O \xrightarrow{R.T.} P + Q$
If the molecular weight of $P$ is less than $Q$,then the incorrect statement is:
