Identify the correct order of acidic strength for the following compounds:
$I$. Ortho-nitrophenol
$II$. Para-nitrophenol
$III$. Meta-nitrophenol

Which of the following is a pair of dihydric phenols?

The major product in the following reaction is:

One of the functional groups present in the product of the reaction between phenol and chloroform in an alkaline medium is:

Match the reaction in Column-$I$ with the product in Column-$II$.

Column-$I$ (Reaction)	Column-$II$ (Product)
$(A)$ Dinitration of $4$-methylphenol	$(i)$ $2$-nitro-$4$-methylphenol + $2$-nitro-$5$-methylphenol
$(B)$ Mononitration of phenyl ethanoate	$(ii)$ $2,4$-dinitro-$5$-methylphenol
$(C)$ Dinitration of $3$-methylphenol	$(iii)$ $4$-nitrophenyl ethanoate
$(D)$ Mononitration of $3$-methylphenol	$(iv)$ $2,6$-dinitro-$4$-methylphenol

Choose the incorrect option based on the reaction:
$(P)$ + $CH_3-CO-Cl \rightarrow (Q)$
Where $(P)$ is salicylic acid and the structure of $(Q)$ is given as:
$(Q)$ is a benzene ring with an $-OH$ group and a $-COO-CO-CH_3$ group at ortho position.
